Whether we kept a certain number of troops there or pulled out completely, if we can't get the Maliki government to include a large segment of its population in its security forces and protection, then the small amount of forces that we would have left there might have slowed this day, but they wouldn't have prevented it altogether.

The Gulf states are happy for us to fight and die. That's good for everybody, but the Americans fighting and dying.

There was certainly merit to the criticism that the deputy attorney general Rod Rosenstein had about how James Comey handled the Hillary Clinton investigation. And I don't think Director Comey ever adequately explained why he treated the Clinton investigation one way and the Trump investigation another.

We need Democrats and Republicans in Congress to work together to fashion a very comprehensive pushback to Russia, not just the cyber-hacking, but their bribery of officials in Europe, their social media campaign, their overt media campaign.

I would need to see changes in the Iraq governance. Otherwise I don't think strikes are going to have any impact and could be very well counterproductive.

The most important thing to me is that the president Donald Trump fired the FBI director James Comey all because of the Russia investigation. That first justification given, again, the White House misleading the country about a major action the administration was taking, but the fact that they had a private conversation in which the president, by his own admission, was discussing the future of Director Comey in that job, and the president brings up whether he is under investigation, highly unethical, at a minimum, unethical.

That bomb that took down that Russian airliner may have been the size of a soda can. And that bomb killed more people than all the Paris attackers combined. So this is still a grave threat.
