Well, you do not understand what security guarantee is either. What you talking about is support. Guarantee is exactly like nato article 5. actual deterrent from the future attack. Economic interest is as unrelated to security as it could be. Lets take an example of trumps economic interest in gaza. That’s actual 180 from security in that case. Also, don’t be naive and think that putin wouldn’t attack america if he had a chance. So far he doesn’t but he‘s well on the way on achieving decades long plan of internal destabilizing usa. Also don’t forget that berings straight is 53 miles in it’s narrowest. Sure, what does trum care if putin attacks alaska 😂
