MHO the "lid on things" are the drones we have to kill those who need to be killed.
We don't need kids kicking in doors looking for ISIS hiding under beds.
I'm also fine bringing US troops home, then what happens happens, it saves us a lot of wasted money.
No, we don't do that, the Iranians and their Militias did that for us, and we turned a blind eye. Now we are whining because the Iranians are running Iraq...
Not to worry, when Trump retreats from Iraq with his tail between his legs, you'll be rationalizing that, too.
What "retreat" from Iraq? That was Obama, who let ISIS run wild. Trump killed ISIS. In case you forgot how much territory ISIS controlled in 2015 see here:
Maximum extent of ISIL's territorial control in Syria and Iraq in late 2015.

The Iranians didn't do shit in Syria, that was the US and the Kurds that destroyed the ISIS Caliphate.
If Iraq asks us to leave we will, otherwise we won't.
If I were you I'd be more worried that Iran starts more shit and gets thumped.
I don't know if Iran has complete control over its proxies, which could be very bad for Iran.
