Well they've passed the resolution requesting we leave, what else do you want them to do?
Iraq gets lots of aid from us. They will cry like babies about that aid being cut off and being treated as an extension of Iran, which the govt seems to have become.
Actions have consequences.
Backing up, any smart team of planners could have foreseen this parliament move as a possible outcome of the attack on the Iranian general. The smart planners are already two steps ahead of this move. Im betting on trump and his planners.
So what's the next move? Refuse to leave?
I personally doubt we will abandon our efforts against ISIS in Iraq any more than we did in Syria, where we were not exactly welcomed by the Syrian govt either.
We weren't there at the behest of the Syrian government, we were there to help the Kurds who were occupying part of the country. Now that we've tossed the Kurds over the side were pretty much there for some reason that isn't clear.
And we may be in Iraq at the request of Iraqi Kurds.
Anyway, its better to see how things transpire rather than speculate.
