It is quite possible that Monday's meeting in the White House could prove even more crucial to the future of Ukraine - and for all of Europe's security - than last Friday's US-Russia summit in Alaska. On the surface, that Putin-Trump reunion seemed to live down to every expectation.

The Trump administration’s crackdown on violent crime in Washington, D.C., has already netted more than 240 arrests and seized 38 guns off the streets, a White House official said.
