thanks for joining us. tonight in a matter of hours, president biden is heading to poland after that emergency summit today in brussels. as the russian invasion of ukraine enters its second month, nato leaders today agreeing on a united front against vladimir putin's aggression. abc's senior national correspondent terry moran is in brussels. terry? >> reporter: hey, juju. at the end of this extraordinary day, one thing is clear. nato is changed. europe is changed. you could feel it in the air. you could hear from it the leaders here. changed utterly by the russian invasion of ukraine. a tougher tone, more determined. a united front like never befor. and president biden at the end of the day telling reporters, that's something vladimir putin did not expect. in conversations with putin before the war in january, biden says he thought that europe would be divided as it has been so many times in the face of his other aggressions. but this time, it's different.

the estonian president declaring really for all the leaders here that a threat to the security of ukraine is a threat to the security of all of europe and they're acting on it. >> terry, thanks. out of that emergency meeting, nato leaders standing firm against russia and agreeing to do more. >> today marks one month since russia began its carnage in ukraine. >> reporter: as the war in ukraine enters its second month -- >> good morning, how are you? >> reporter: president biden arriving at nato headquarters in brussels today, gathering with world leader as part of an emergency summit to discuss the next steps in response to the russian invasion. >> i'm announcing united states is prepared to commit more than $1 billion in humanitarian assistance. >> reporter: in addition to the aid, biden also promising to grant asylum to 100,000 ukrainians seeking refuge in the united states. while imposing fresh sanctions on some of russia's wealthiest elite.

>> more than 300 members of the duma, on the ground lil gaurks, and russian defense companies that fuel the russian war machine. >> reporter: president zellensky in a virtual address in part requesting further military aid, asking nato members for 1% of all your planes and tanks. as concerned grow putin may resort to using chemical weapons in the next phase of combat. >> we would respond. we would respond if he uses it. the nature of the response would depend on the nature of the use. >> as president putin is increasingly pressed in the conventional fight, where his forces have underperformed, and he has not attained sort of the quick win objectives that his campaign was intended to perform, he has hinted rhetorically that chemical, biological, even nuclear weapons might be on the table. >> reporter: after a month of fighting in ukraine, the losses

can be calculated in so many ways. despite what vladimir putin may have initially believed, ukrainian forces have mounted a fierce collective resistance. >> even though on paper the ukrainian military should be overwhelmed by the russian military, on the russian side you're seeing sort of an underperformance. even bordering on military incompetence. >> reporter: this morning, ukrainian forces saying they've destroyed a russian ship at the occupied port of berdansk. verified video circulating online showing the ship burning. the ship, they say, carried weapons and ammunition to continue the siege of mariupol and prevent evacuations. but as the weeks turn to months and the losses continue to mount, ukrainian leaders are desperately pleading for any help in their fight. a delicate dance as nato countries try to address ukraine's need without

escalating the conflict into an all-out world war. on the border of poland and belarus, this is not a battleground, but a nato training exercise. in a far-flung corner of the countryside, the silence is shattered by gunfire. with nato leaders approving four new battle groups to bolster defenses in several countries, abc news was granted exclusive access to these exercises along the polish border. this exercise takes place twice a year, but of course this year is different. the poles will tell you boldly, it's more than an exercise, it's a show of force. >> reporter: miles from the border with belarus, tens of thousands of russian forces amassed before invading ukraine. a polish brigade commander tells my colleague, martha raddatz, they are on high alert. >> how likely do you think it is that the russians would attack poland? >> no one knows. we were told that they don't

attack the ukraine. >> reporter: these are soldiers with california's national guard. they're alongside hundreds of other american soldiers in poland, supporting nato. >> it's difficult to watch and not be able to do anything. because we're direct action-type people. we all are humans, you know, and no nation should stand alone when they're in need. >> reporter: a show of force, but for a people desperately in need, that may not be enough. before our eyes, a humanitarian nightmare unfolding as multiple ukrainian cities still face the devastation of a russian onslaught. katrina fled mariupol, besieged by russian forces, with her husband and daughter in tow. she had to leave the rest of her family. she spoke with my colleague james longman. >> what did you feel as you were leaving, to leave your family behind? >> you are leaving, and your family is staying. and you don't know if they're alive at this moment, even. >> reporter: even that journey was perilous. >> tell me, so is this a bullet?

is that from a bullet that was fired on you? >> yeah, fired. >> so it was -- wow, there's a hole in the bonnet there. >> yeah. it's a hole. and i was sitting here. >> reporter: fortunately, for now, they are safe. yet, like the millions of people who have already fled their homes across the country, they're looking for hope in whatever comes next. james longman joining us now from lviv. james, as we saw, mariupol is getting battered. what can you tell us about the situation there? >> reporter: the siege continues. something like that 100,000 people still there. very little access to food, to water, to basic necessities. but cynically, the russians have started opening what they're calling humanitarian centers to provide aid to people. so you've seen big, long lines of people queueing up to get food, to be given shelter. these are the very people who took these things away from

them. >> from the outside looking in, it's as if the entire country has become a war zone. what's it like on the ground there throughout the country? >> reporter: juju, it feels as though ukraine is really on the offensive. it's an extraordinary thing to think, you know. just at the beginning of all this, all that time ago, a month ago, vladimir putin thought he was going to be able to take kyiv in a few days. a month in, his forces have been pushed back to the east of kyiv 14 miles or so by ukrainian forces. so just about all over the country, ukraine is on the offensive. but vladimir putin has the wherewithal to keep this going. >> yet if ukraine is going to continue to be on the offensive, we heard today from nato leaders that more aid is en route. what does that aid look like on the ground? can it make a difference? >> reporter: it absolutely can make a difference, juju, and it has made a difference. it's kept ukraine in this fight and that's why president zelenskyy wants more of it. that's why he was saying to nato leaders today, please just give me more help. what he's had in mind is, you

know, a no-fly zone. he would love for there to be nato troops here. i don't think either of those things are going to happen. but as long as military assistance can keep coming, he can keep taking the fight to russia. >> james longman reporting from lviv. we're grateful to you. please stay safe. >> reporter: thanks, juju. up next, olivia rodrigo, the brand-new megastar doing her own thing. for people living with h-i-v, keep being you. and ask your doctor about biktarvy. biktarvy is a complete, one-pill, once-a-day treatment used for h-i-v in certain adults. it's not a cure, but with one small pill, biktarvy fights h-i-v to help you get to and stay undetectable. that's when the amount of virus is so low it cannot be measured by a lab test. research shows people who take h-i-v treatment every day and get to and stay undetectable can no longer transmit h-i-v through sex. serious side effects can occur, including kidney problems and kidney failure.
