Correction: It is a matter of not going into their nest to start with, unless a substantive present-day or future threat exists, which it is in our best interests to squash.
It is not safe for us to slip away back into early 1900s "Isolationist" mode, as you would have us do. The world has changed, and become a much more dangerous place. It's far too late to fall back on old and discredited foreign policy methodologie3s.
Actually, there's a big difference between being an isolationist and getting involved in someone else' civil war...
Agreed.
...In 1900, we were trying to do the exact same thing you advocate today in the Philippines. We sent a huge army over there and fought a ten year war against the Filipinos who didn't want us there. President McKinley, who couldn't even find the Philippines on a globe said that we had to go over there to Christianize them. (Forgetting that 90% of Filipinos were Roman Catholics.) The end result of the thing was a war that killed 4000 Americans and 100,000 Filipinos...
Disagree.
In 1900, we were hip-deep in the earliest phase of a New Era American Imperial Destiny - it is the stuff that the Spanish-American War was made of - and, after seizing the Philippines from the Spanish, we decided to pacify the Philippines so that we could utilize it as a forward military base in the Asian-Pacific theater of operations - devising
White Man's Burden -type juicy rationalizations, in order to justify our presence and operations there.
Hell... I view the Spanish-American War, and our seizure of both Cuba and the Philippines, even more harshly and unfavorably than you probably do.
...Flash forward Sixty More years, and we were in Vietnam, trying to prop up a government of French Quislings over Nationalists heroes who happened to be Communists. after killing more than a million Vietnamese and losing 56,000 of our own, we finally got chased out. ...
Oh, stop trying to canonize Ho Chi Minh, will you? Nobody's buying it. At the time, any non-Communist government was preferable to a Communist one, during the days of the Cold War, when every Win and every Loss meant far more for future prospects than we give them credit for now. Nevertheless, we backed a Loser, and it cost us dearly, and was, in that respect, a very great Mistake - but mistaken more for our poor assessment of prospects and outcome than in choosing sides.
...Now, here we are, 50 years after that, 14 years after 9/11. Still trying to win civil wars that have nothing to do with us, a lot of which we caused...
We're out of Afghanistan - or very close to it, and are no longer engaged in independent combat operations.
We're out of Iraq altogether.
The former was a 'righteous shoot' but we should have been in and out in 6 months, not 13 years, and we should have killed bin-Laden et al in Tora Bora.
The latter was an 'un-righteous shoot' that squandered American blood and treasure for no good reason, and it left a vacuum into which ISIS has flowed.
ISIS-ISIL-IS is a threat to Mankind at large.
We did, indeed, have a hand in creating the conditions by which it was spawned and by which it originally prospered, but this was by no means exclusively or even primarily our doing or our fault.
But, with respect to the culpability that we DO have, we owe it to ourselves, and the rest of the world, to participate in its destruction or neutralization.
Consider it 'Aftercare' for Iraq, and 'Preemptive Intervention' for Syria and the rest of that lot.
If, by some chance, the Arab-Muslims of the region manage to get off their dead asses and take care of this themselves, all the better.
But, one way or another, the job needs doing, and, if our so-called Arab allies cannot do this in a timely and decisive manner, we must be prepared to participate far more actively.
ISIS-ISIL-IS is far too dangerous a Beast to allow to thrive... far better to stop Hitler at Munich in 1938, then to limp-wristedly deny the Elephant in the Room.
...
When 6,000,000 of your own People - men, women and children - have been slaughtered - you'll have a place at the table with such a position.
They weren't killed by Palestinians or Arabs. They were killed by Good Christian Germans wearing buckles that said, "Gott Mit Uns". so, no, it isn't an excuse for what they are doing in Palestine...
Who the hell cares about Palestine?
We're talking about ISIS-ISIL-IS... the 10,000 lb Elephant in the Room.
Israel-Palestine is a sideshow in this context... there are much bigger things at stake than the pissant Palestinian knuckle-scrapers.
