Is US capable of another war if required? (Iran or NKorea)?

Yes, militarily wise, we can. Moral wises i dont think so, since iraq, the population has turned into a buch of yellow-belly cowards who would rather give into the the demands of such dictators than risk having to fight and die. the american public are cowards and dont have the resolve for another war. Its sad really we beat Germany and Japan, with 200,000 casualties,in 4 years and we bitch about 5,000 dead over 5 years...Not to mention the Defeatist and appeasment party is in power.

I think so, but the real fear is that either would be a nuclear war...a protracted conventional war would be more costly in terms of both casualties and dollars. Either scenario is scary.;-|

I'm 39 and I'm prepared to do anything necessary for our country's welfare... except cut my nails... lol - I'm a guitarist - but no really, I'd do anything asked by the President sans causing harm to any American or ally

Yes, but be prepared for a draft if we do.

we would send the nukes. it would be a short war.

Iraq and Afghan was a waste of money. It was a wrath against religious terror.
