Hang, I'm not forgetting history. Far from it.
However, the world HAS changed. Things are different than they were 60 years ago. The UN, piss-poor though it is, is far more effective than the League of Nations was. There is a collective history for all of us that wasn't there in '39. The world has seen what madmen on the march can do and not that long ago. Saddam gave a quick refresher course not long ago.
You'll note that in my above arguments I mentioned US forces that could deploy to support UN authorized actions.
I just no longer think it's necessary that the US be the ONLY policeman out there on the streets.
The critics that have been hurling the rotten fruits and vegetables deserve their chance to walk the easy beat while we cool it in the station house for a while.
Turnabout is certainly fairplay in this case.
Sandman's being a bit disingenuous when he suggests deployed forces are no more expensive than those based at home. Any time you stretch out supply lines, costs go up dramatically, in many areas.
You mention ignoring the "threat". Where? Where is the threat that requires us to maintain nearly 20% (probably more since I last checked a while ago) of our huge military in a deployed status?
Europe? NATO is still there; where's the opponent that can overrun the NATO nations even without us basing troops in Europe?
Asia? We couldn't stop China in a non-nuke land war in any place we tried. Our supply lines are way too long. (Same problem any would be attacker of the CONUS faces.) So that would be foolish. If it goes nuke, the B-2's are in Missouri anyway.
Korea? Been there, done that. Time for the ROKS to be at least as tough as their poor neighbors to the North. I'm CERTAIN the UN would send troops anyway, right?
Doesn't have to be just us. We've got what, 30,000 troops on the DMZ? As if. You'd still be behind the power curve if the balloon went up.
Same for Taiwan.
Israel/Palestine? You KNOW we're not getting into that mess.
Iraq and the Gulf? Been there, done that. Same deal; we don't keep enough troops there to stop anything. They'd have to be reinforced. Again, I'm CERTAIN the UN would act and send troops as well.
All in all, we don't need a military the size that we have now. No where close to it, in fact. Enough to defend the US and additional to provide a creditable rapid deployment force to augment the rest world community's forces when the UN chooses to act.
"All we are sa-a-a-a--a-a-y-y-y-y-ing is give PEACE a chance!"
Beat your sword into a plowshare, brother. We've reached the promised land and the rest of the world community is going to step up and do their fair share. Sleep well tonight; the UN is awake.
