"Ukraine made the decision to completely denuclearize. In exchange, the U.S., the U.K. and Russia would guarantee Ukraine's security in a 1994 agreement known as the Budapest Memorandum." [0]
We can see this security guarantee in action right now. Same will happen with NATO's mutual defense guarantee.
> No NATO state will enter into this conflict, Putin has been pretty openly threatening with nuclear annihilation
This basically means 2 things:
1. NATO is dead.
2. Putin is free to do whatever he wants wherever he chooses.
Definitely not a solved problem. My bose qc35 II headphones constantly drop connection or connects to my ipad instead of my laptop. The sound quality is trash but I'm ok with that as I got them for active noise cancellation. ANC works great I must admit.
