Cato takes apart the idea of redeploying to Kurdistan. I’ve always felt this was something being tossed off by ignorami as a way to withdraw without withdrawing.
Another reason that this commentary misses is strategic. Kurdistan is land-locked. If Iraq turns ugly, the only way to get out is through Turkey. And I’m sure they’d be delighted to have tens of thousands of troops and thousands or armored vehicles marching through their country.
