Ukraine is getting a lot of help with money, food, weapons, training e.t.c. US just donated 600m to Ukraine.
This isn't just about Ukraine and Russia any more. A lot of the world has basically told Russia to do-one. There's also cyber warfare happening against Russia, which is looking like it's successful. You can't access anything inside of Russia now online wise. It's all been taken either offline or network segmented so only internally you can access it.
Apple Pay has also been stopped in Russia. There's a lot more stuff happening worldwide.
NATOs response is - Touch another country that's in NATO and you will feel the wrath of NATO, full force. Because of the rest of the stuff happening behind the scenes Russia is doomed.
There's a lot more wars going on that's not on the ground/air as such.
The troop war isn't the end of it regardless of who wins.
