That's Trump, not Musk.
Also, I think terrorism is something completely else than the context you're giving. This is geopolitical, not terror.
Europe should just react by making Canada a part of the Union, and then the Union can build vast military complexes in a few places in Canada. I am positively sure the U.S doesn't mind a gigantic foreign army on their borders, that's after all what they for many decades had in mind with NATO on the borders of Russia.
Make North America EU again.
Has a nice ring to it wouldn't you say?
Yes, I would quickly warm to a far more extensive alliance with Canada. Perceptions of many aspects of culture and social market economic systems are shared between Europeans and Canadians. The traditional significant intertwining of economies between the U.S. and Canada is now showing signs of unravelling, despite the close geographic proximation.
Of course, the topic is complex. But I feel that a tightening of the EU/Canada alliance could be mutually very beneficial. Actually, THE Transatlantic Alliance is NOW with Canada and Mexico rather than with the U.S. The former one with the U.S. has now been so seriously damaged that one now wonders whether it could EVER be revived in the future. Still, I am grateful for "Team Trump" giving us previously sleepy Europeans the rudest of wakeup calls. It was long overdue. And now, we have NO choice but to get our act together tout de suite and become hardcore machiavellian (which is not "very nice", but we need to serve our own interests FIRST-and screw the rest of the noise).
