I think we've blown this situation in the Middle since it developed at the end of British Colonization. We can't even trust our allies there. A war that never ends is great for the industrial military business and many against this I am sure are heavily compensated. Russia wants a crack at it, and people fear them filling the vacuum once we live. But we really never were in control of the area, and have deceived ourselves in thinking that we were.
I have mixed feelings on the issue, we leave there will be a power vacuum filled with China and Russia. But then they were inherit these unreliable allies and the never ending war and the animus that comes with being an occupier that caused these terror attacks in the first place. They will inherit the cost of these wars as well which have increased our debt to high levels with little geopolitical results.
Of course, other countries are against it, because they use us as the World Policeman. Of course, Mattis, Graham, Cohen, Cheney and guys like Rumsfield are against it because they are lobbied heavily by the industrial military complex. I think Russia and China may get more than they bargained for just we did when we filled the void of the British leaving.
I, among others, made no statement of agreement or disagreement about Trump's move. Many of the comments (and my concern) is that there seems to be an overwhelming number of informed people (as opposed to uninformed people like me) on both sides of the aisle who think Trump's move is premature, shortsighted, and will result in an ISIS resurgance since they actually haven't been defeated. It concerns me when people that I presume to know more about these issues than I do, people like Jim Mattis, Lyndsey Graham, William Cohen and dozens of other well-informed Rs and Ds have responded negatively and fearfully. Rand Paul, who I disagree with on many things but respect as an intelligent person is, as expected, in agreement with the move.
Yet, these folks I would guess are not people whose opinion you would value normally. But they go against Pres. Trump and all the sudden they are wise counsel. Be honest is this the case.
There are going to be consequences if we stay, or if we leave regardless. In many ways this is a no win situation.
Never get in a land war is Asia, could just as easilty be never get in a land war in the middle east.
