Emboldened by Donald Trump's win and inauguration, several of Europe's top populist leaders gathered in Germany this weekend to strategize on how they might help each other in their upcoming national elections.

Marine Le Pen, who heads France's far-right National Front, proved especially popular with the largely German crowd that packed a convention hall yesterday in the historic western city of Koblenz, nestled between the scenic Rhine and Mosel Rivers.

The 3rd Armored Brigade Combat Team, 4th Infantry Division, from Fort Carson, Colo., has begun moving into Poland as part of the biggest U.S. military deployment in Europe since the end of the Cold War.

It's part of an Obama administration effort to deter perceived growing Russian aggression in Eastern Europe. The Kremlin isn't happy.

"These actions threaten our interests, our security," President Vladimir Putin's spokesman Dmitry Peskov said. "Especially as it concerns a third party building up its military presence near our borders. It's not even a European state."
