c.e.o.'s and their companies are abusing their position and crippling the competition many of the practices used by these companies have harmful economic effects they discourage entrepreneurship destroy jobs high cost and degrade quality simply put they have too much power what for hours these big tech c.e.o.'s addressed allegations including abuse of power by data survey lines and political censorship why does google steal content from honest businesses i disagree with that characterization just last week or many many small businesses in fact today we support one point $4000000.00 small businesses are supporting over $385000000000.00 and they are economic activity amazon has nearly 7 times the market share of its closest e-commerce competitor one seller told us that and i quote amazon continues to be the only show in town no matter how angry sellers get

they have nowhere else to go so are you saying that these people aren't didn't go when they say that amazon is the only game in town. congresswoman with great respect i do disagree with that i believe that there are a lot of options cooking the soccer bergan system their companies aren't invincibles we don't have a dominant share in any market or in any product category where we do business new companies are created all the time all over the world and history shows that if we don't keep innovating someone will replace every company here today and that change can often happen faster than you expect also on this play partisan divide on this cut to the chase big tax out the conservatives that's not a suspicion that's not a hunch that's a fact republicans say these companies are unfairly suppressing and censoring conservative opinions in media but democrats say big tech isn't going far enough

and cracking down on misinformation and hate speech. the united states is a veiled plans to withdraw a nearly 12000 troops from germany a 3rd of its military footprint in the country as a trump justify the move saying germany hasn't been paying enough for its defense taking advantage of the u.s. german leaders expressed regret at the decision. a historic reduction in the number of american troops stationed in germany even more will be leaving than expected. the u.s. secretary of defense mark asper announced the withdrawal downplaying its significance it is important to note that in nato's 71 year history the size composition and disposition of u.s. forces in europe has changed many times but u.s. president donald trump said the move is meant to send a message to germany. for. this feeling

but it's not that simple while it's true that the u.s. pays more toward the nato budget than germany the german government has promised to match u.s. contributions beginning next year at 16 percent of the total nato budget trump often points out that germany does not meet a nato guideline that all members should spend 2 percent of their economic output on the fence germany only spends 1.4 percent but that guideline refers to spending on each country's own military not directly to nato medo members are now seeking answers as to how the new u.s. plan will be carried out and what it will mean for the future of european security there has been pushback from the u.s. congress and analysts say even the pentagon was reluctant to carry out trumps demand for troop withdrawal you can imagine the arguments and the discussions and disagreements that would have been going on back in washington inside the pentagon and with the white house but at the end of the day the president says we're going

to do this and so the department of defense it was ok well here's here's how we're going to do it there are about 24000 u.s. troops will remain in germany but some observers worry trumps costly message to its nato allies could weaken the whole alliance. so president trump is pushing ahead with a plan to pull out despite criticism from nato allies and resistance at home as washington correspondent all of a salad explains why. donald trump is punishing germany for not spending enough on defense that's at least what he's trying to make the american voters believe and it's true germany promised over and over again to raise its defense budget to 2 percent of the country's g.d.p. but hasn't fulfilled the promise yet the truth is also donald trump's polls are continuously deteriorating as we get closer to the election and he wants to deliver results on a threat he has made many times throughout his presidency lawmakers on both sides

now say that trump is rather hurting nato and america itself arguing the troop withdrawal is nothing but a campaign stunt and it might not even be brought to success there are many hurdles to be taken a bipartisan movement in congress is currently trying to block the withdrawal and time is running out and a potential president joe biden feels differently about the transatlantic partnership. is this being seen on the other side of the atlantic in germany we asked our political correspondent simon young. the german government i think biting their lives the foreign and defense ministers released a joint statement the seedlings saying just that they had taken notice of this decision and that they would be consulting with the affected regions in germany but also with the u.s. government and with nato partners but there has been some sort of disappointed reaction from some politicians for instance the varian state premier marcus. he said that this is the wrong decision that it weakens the u.s.

and nato in their military interests of bavaria of course he is an interested party here because the u.s. base at graf and in bavaria is the law or just overseas u.s. army base in the world and others within the political scene here in berlin really quite disappointed pointing out that you know the u.s. presence in germany is not about defending germany primarily it's about the u.s. or operational capability and the logistics base. in the region and around the world which is proven and established here in germany now to some of the other stories making news around the world. hong kong police have arrested 4 students for alleged offenses under the territory's new national security law they're accused of organizing and inciting secession beijing imposed the sweeping security law on july
