It kinda does matter. He is very literally referring to trade just as much if not more than military intervention here and elsewhere. “Globalism” is far more than just foreign policy as it relates to our national security. The two concepts are inextricably linked.
The same thing that always happens when a power vacuum is created. Someone, like Russia or China, or ISIS will fill the void. China’s already moving into the south China sea like they own the place. Russia’s already moved into the Ukraine. Pulling out of these regions isn’t going to help the situation. What if Iran acts up, do you think Russia will step in? Doubtful since they’ll selling them weapons…
It isn’t in our best interest to allow China or Russia to increase their influence on Europe for numerous reasons not the least of which is economic influence.
That’s fine, you asked the question.
