host: missy ryan covers the pentagon for reuters. the russian invasion took place in the late 1970's and early 1980's. guest: there is some evidence of iranian support for insurgents in afghanistan. i think it is unclear. it is a much more distant relationship than the relationship, if we're talking about outside powers, with pakistan. host: warren joins us from ohio. collor and i think the previous caller said head on most of it. isn't afghanistan the graveyard of empires? what makes us so arrogant as to think that we can bring up a middle ages country, or dark ages country, into the 21st century and make it stick? i do not understand that. and iran is up, for insurgents coming in. the government has already admitted that it is a pass 0.4 fighters to comment, not to mention the other weapons. another thing, about weapons, the kill cost ratio, the rocket- propelled parades, look at a cost of weapons systems that they can destroy and bring down. a cheap portable weapon, and we cannot fight a war like that. host: thank you for the call
