In case you have been wondering why French President Emmanuel Macron recently declared NATO brain dead, there's a very good reason and simple explanation for that.

As one saw at the beginnings of the NATO summit in London on Tuesday, it is none other than U.S. President Donald Trump who is now out there defending NATO and criticizing the French president for having declared the alliance brain dead.

You have to give it to French diplomats. They are very crafty in their approach to their business.
