seem to be unlikely allies.

The United States will cease all implementation

of the non-binding Paris Accord.

It is an actual mistake — both for the U.S. and for our planet.

The Iran deal was one of the worst

and most one-sided transactions.

To officially recognize

Jerusalem as the capital of Israel.

I thought that it was a mistake.

Macron, a young centrist, had won the French election

by rejecting far-right anger.

Trump had supported his rival,

the staunch nationalist, Marine Le Pen.

The two presidents' first encounter

last spring was awkward.

Trump extended his arms in greeting, but Macron

first approached Angela Merkel.

And when they did greet each other,

Trump gave Macron of his famous arm yanks.

Their handshakes would come to take on a life of their own.

What's being described as an epic handshake standoff.

Alpha male kind of engagement.

That's what I call a French press.

I think we just surrendered to France.

It was the beginning of Macron's political courtship of Trump.

Other European leaders, like Angela Merkel and Theresa May

have been wary of Trump's inflammatory rhetoric

and periodic taunting of some of the United States'

most trusted allies.

We work together does not mean that we are afraid to say

when we think the United States has got it wrong.

Retweeting from Britain First was the wrong thing to do.

Macron has mostly tried a pragmatic approach.

He shrugged off some of Trump's provocations.

I think we should not overplay the situation and his tweets.

At Bastille Day, Macron

impressed his American counterpart

with a military parade in Paris.

One of the greatest parades I've ever seen.

And a promise of unconditional loyalty.

There was also the 30-second handshake.

Macron seemed to make a point of saying

he and Trump were in close contact.

I call him very regularly.

Probably three to four phone calls during the past weeks.

We have a very good relationship.

But why would Macron so openly embrace

a president who's unpopular at home and abroad?

It's an attempt to burnish his reputation as a leader.

It's also to bolster the perception

that France is the key middleman between the United States

and Europe at a time when the United Kingdom is grappling

with Brexit and Merkel is struggling to hold onto power.

But those are intangibles.

On the harder issues of policy, experts

say Macron's efforts to try and sway

Trump on everything from the Iran deal to climate change

have so far come up short.
