Soros is always uncomfortable for conservatives and liberals alike, including me. I don't agree with half of what he suggests here. For example, in my opinion, this conflict is simply about power and not about right or wrong. Furthermore the tone feels quite aggressive.
The key point he makes is correct, though: The west can't achieve its goals, if it is not willing to fight, either by investing enormous amounts of money into Ukraine, or by a military intervention. We should probably go for the first or accept that Ukraine is lost.
