Europe should not rely on us. The cold war has been over for 30 years. The soviet bloc is long gone. Russia has proven it is a paper tiger, as evidenced by their inability to defeat Ukraine. The fact that Ukraine has inflicted so many losses and caused so much damage is an embarrassment to Russia, the Russian military, Russian tactics, and Russian equipment. I doubt they would stand a chance against European countries. In addition, Russia’s military has been so devastated by this conflict they will not be able to mount any sustained offense against anyone for 10-20 years. They are not a real threat to Europe anytime soon.
