After what's happened in Ukraine it sure seems that all alliances, pacts, agreements are not worth the paper they're written on, in reality, and were only ever "maybe"s.
The 64 dollar question is:
If Putin/Russia, having basically turned Ukraine into rubble, decides it's time to take Poland and invades it by air, land, and by sea from the North, ...will Biden/US, Boris/UK, and the other NATO countries get into a full blown war with nuke-armed Russia (Putin threatening to use nukes)...or will appeasement still rule?
