Because the United States is launching a limited missile strike to deter them from using Chemical Weapons again. The United States is NOT launching any sort of an invasion to topple the regime. Also, launching 300 cruise missiles would only be a fraction of the amount of munitions Syria has expended so far in its war against the rebels.
You keep referring to "300 cruise missiles" as if you got that number from somewhere, but you just --- pulled it out of the air, didn't you?
You don't know what is going to happen. No one does.
Hopefully nothing.
You don't know what the point is, if we did make an attack. A punitive small raid? A punitive big raid? A raid to impair enemy capacity? A decapitation strike? Shock and Awe? An escalation into Iran? You don't know because you aren't in the White House or the Pentagon. How do you know there wouldn't be an invasion to topple the regime? There was with Iraq II.
You don't know how much and which munitions Syria has expended.
Not that it matters. You seem to suppose we ought to shoot as much at them as they shot at each other? Does that make ANY sense??
No.
None of this matters, if we can stop the attack on Syria. Not that I care a penny about Syria, of course, but I do care about not going on and ON with all these long losing forever wars. Especially a new one with Iran, which is presumably the point of any attack on Syria.
