Breaking news is that the Iraqi parliament has passed a non-binding resolution calling for the withdrawal of foreign troops:
The non-binding resolution was passed by the Iraqi parliament after the caretaker Prime Minister, Adel Abdul Mahdi, called for an end to the foreign military presence in a speech to MPs.
The resolution calls on the government to revoke its request for assistance from the international coalition fighting IS due to "the end of military operations in Iraq and the achievement of victory".
It says "the Iraqi government must work to end the presence of any foreign troops on Iraqi soil and prohibit them from using its land, airspace or water for any reason".
[...]
Ahead of the vote, the prime minister said the US military presence in the country should be ended as soon as possible.
Ending the US military presence in Iraq was "better for reorganising healthier and correct relationships with the US and the rest of the states", Mr Abdul Mahdi said.
Since the Iraqi government and parliament seem to concur on this, unless it is a face-saving measure for (internal) public consumption that will somehow not be translated into a request to foreign governments, it looks like the US military presence in Iraq is under threat.
I'm curious however what is the legal nature of this presence? Are there any US bases in Iraq with long-term leases, for example?
