This is a very interesting situation. You can be in the United States of America and practice your 'freedom of speech' by antagonizing people of other nations.

Some small town pastor of a small town church decided to appeal to the radical elements of his church by antagonizing the radical elements of people in a different nation. And the poor United States of America does not know how to respond to this. It doesn't want to support taunting people in a different nation/religion. But it doesn't have the power to shut its own people up.

America has many "spoilt children" like the above pastor. America does not have the power to discipline the pastor. But America has sworn to protect people like the pastor, no matter how radical of a statement he makes.

My guess is that this situation is going to escalate.
