Ukraine is no longer a factor Tommy. Territory that was the Ukraine is. I think GB will be one of the last to opt out, but may not.I think that might be the solution and I think Ukraine has offered a proper referendum. It has to be on a proper democratic basis though, Not the product of an illegal invasion.
Something that could be considered is the possibility of America interfering directly to stop Russia's sure progress.
Russia shouldn't have entered the war in a gentle manner. That gave the impression that Russia is weak and was a small bankrupt the defeated nation.
And another factor to consider is if America escalates then China will take part and America can then be said to be playing second fiddle forever.
Biden is taking precautions to keep China out and neutral. The demonizing of China by America was defused and put to bed suddenly over the period of no more than a month!
