Big on warnings….
Check it out:

President Obama on Friday delivered a tacit warning to Russia’s Vladimir Putin amid the unrest in Ukraine, vowing at the close of a NATO summit that the allies will not tolerate an attack on any member nation.

“An armed attack against one shall be considered an attack against them all. This is a binding treaty obligation. It is non-negotiable,” Obama said at a press conference. “Here in Wales, we’ve left absolutely no doubt we will defend every ally.”

The warning in Wales comes as the U.S. partners with other nations to bolster their presence in Eastern Europe.
