Obama: Trump's NATO comments show 'lack of preparedness'

WASHINGTON (AP) — President Barack Obama says that GOP nominee Donald Trump's recent suggestion that the U.S. might not come to the defense of NATO allies is another sign of Trump's "lack of preparedness" on foreign policy.

Obama responded: There is a big difference between challenging our European allies to keep up their defense spending, particularly at a time when Russia's been more aggressive, and saying to them, 'You know what?

Another factor, he said, was "personal discipline in terms of doing your homework, and knowing your subject matter, and being able to stay focused."

[...] to make all this work "you have to really care about the American people... not in the abstract," Obama said, noting that is crucial because that will help ground the president in that difficult job and prevent them from being overly influenced by polls, pressure and difficult developments.
