Donald John Trump now vows to be Vladimir Putin’s “worst enemy” if the men’s attempts at friendship fails.

Sure. I’ll buy that. Actually, I won’t.

You see, the president has been handed every opportunity already to become the Russian president’s “worst enemy.” He has taken a pass.

You saw that astonishing press conference in Helsinki. Trump had a chance to confront Putin on the world stage. He didn’t. Instead, he said Putin’s denial of attacking the U.S. political system in 2016 was “very strong” and “powerful.”

Trump has hit back at the critics. He said something on CNBC about those who have said he should have been tougher on Putin. Trump offered some goofy straw man, asking whether his critics wanted him to walk over to Putin, get directly in his face and yell at him.

Of course not, Mr. President.

All many of us want is for you to look Putin in the eye and say, “Mr. President, we will not stand for your interfering in our electoral system. Americans consider that a hostile — and I am one of them — and we will respond accordingly.”

He didn’t do that … apparently. He stood there and then rolled over.

Now he contends that he’ll be Putin’s “worst nightmare”? Give me a break.

Yet again, he takes another shot at former President Obama, who he has called a “patsy” in his relationship with Putin. Oh, brother. The president needs to give that one up, too.

The president so far has demonstrated a profound reluctance to talk straight to this nation’s adversary. Tough talk to American media won’t do the job, Mr. President.
