Sadly, AI, you are right, though you didn't carry it to its conclusion.
You can't dabble with war in an area that has been in a state of war since the Biblical times without some of it spilling out on your own front door.
This statement is known to be true in so many ways. We should remember the Vietnam war. (Excuse me, "police action.") We should remember Operation Desert Shield. As you gave a disclaimer, AI, so I have to give one: Take in the WHOLE paragraph before jumping up and down on my stuff.
You do NOT dabble in war. If you have an enemy then you don't dabble around. You eliminate the enemy completely. It is the macrocosm of the first rule of owning a gun. If you take out your gun, you had already better have decided to use it. It has no business being out as a threat. If we didn't want to eliminate an enemy then we should never have gotten involved. War isn't about slapping down miscreants. War is the systematic elimination of a threatening force that, if left intact, has great potential to do harm. I say again, if you are not willing to ELIMINATE the threat then you have no business in the threat area. If we had gone in and blasted the terrorist camps into smithereens and laid it at the feet of the host countries that NOWHERE in their pipsqueak sheikdom was safe unless they started to control their unruly population, I think the idea might have gotten across. Does that sound barbaric? You're DAMNED RIGHT it sounds barbaric. But then, when dealing with barbarians, you have to speak their language.
I'm not disagreeing with what I quoted from you, AI. I am merely pointing out that it was incomplete. And from what I said, you might infer that I am a bit hawkish. Having watched what happens when you try to play like a dove and get neither respect nor results, I recognize when escalation is needed. You don't have to agree with me, and probably won't.
As a side effect, if we had taken a more suppressive action earlier, a lot of the refugees wouldn't be running from an area controlled by thugs and hoodlums and warmongers. The outflow might have been at least partly reduced.
