"we will gradually lose our alies because they will not trust us."

Huh????? Fer Chrissake, they don't trust you now! ;-D (Except maybe for Israel.) The USA is one of the least trusted nations in the world, and I mean just about everywhere. Your allies are not allies out of a sense of trust, pdq, they are allies due to various almost inextricable financial and business ties that have been around ever since the end of WWII, if not longer. It's sheer pragmatism and the weight of the status quo, not trust.

Nor, of course, do they trust Russia. Nobody has much reason to trust either the USA or Russia.

Nobody trusted the Romans either...for the same reason. They were not trustworthy.
