and not a small amount of anger.

The decision by President Trump to tear up

the Iranian nuclear agreement is seen

as one that's both dangerous for the region, for the world,

and one that's entirely unnecessary.

It puts a question mark over the transatlantic relationship.

Some diplomats are describing it as the biggest rupture

in transatlantic relations since the end of the Cold war.

The nuclear deal with Iran should stay.

That is also the view that is shared

by Chancellor Merkel of Germany and President Macron of France.

There have been differences before over climate change,

trade, over the Iraq war, but this one

seems qualitatively different.

The whole of Europe, if you like,

is united in opposition to Mr Trump's decision.

The nuclear deal is not a bilateral agreement,

and it is not in the hands of any single country.

The nuclear deal with Iran is the culmination

of 12 years of diplomacy.

It belongs to the entire international community.

What does it say, allies are asking

- whether it's Canada or Japan or Australia or India -

what does it say about America's word?

What does it say about America's willingness

to uphold the international system, the rules-based order,

which the United States itself created after the second world

war.

On the one side now, you have, it looks like, the US,

with the support of Saudi Arabia and Israel,

and, on the other side, more or less, the rest of the world.

That's not a good position for the United States to be in.

But that's not a good position either

for the western liberal democracies.
