Donald Trump actually said...

Iran doesn’t want to speak to Europe. They want to speak to us. Europe is not going to be able to help in this one.

I don’t like the fact that Israel went out this morning at all, and I’m going to see if I can stop it.

any retaliation by Iran against the U.S. would be met with a force far greater than that used in the weekend U.S. attacks.

I think they both violated it.
