If that causes WW3, then WW3 was going to happen anyway.

It would've been better to take Nazi Germany on in the Sudetenland '38 when it's forces were weaker, than in Poland '39, or worse still France '40, when they were stronger.

Ukraine has bled Russia dry of ground forces. There are no infantry, mech, tank, or artillery units facing Nato, only air & AD 👇.

There are also no Russian ground forces in Crimea, only air, AD, & ships blockaded in harbour 👇.

But there's no need to even put boots on the ground in Ukraine or drive to Moscow as Prigozhin did, these will finish Russia by the end of 2025:

1. Maximum sanctions on Ru
2. 100% export tariff on Ru
3. Oil $30 a barrel
4. $300bn frozen Ru assets to Ukr
5. $100bn EU import tariff to Ukr
6. $500bn US lend-lease to Ukr
7. 1m+ 18-25 Ukr reserves call-up

As soon as Zelensky signs the minerals deal, Trump will inform Putin of the above 7 sticks to beat him with and demand land back for Ukraine, especially along the Kherson, Zaphorizhia, and Crimean coastlines for US LNG terminals.
