The statements from Lavrov, the Russian foreign minister yesterday are very concerning indeed. he has gone the full Comical Ali. The West is at fault, Ukraine are holding hostage their own people, using human shields, preparing chemical and nuclear attacks. All whilst Russia now vows to turn East and never deal with the West again.
This is very dangerous territory indeed. There is no bakcing down from Russia and no sign that Ukraine is going to capitulate anytime soon either. the nastier the war gets, the more the pressure from the population of Western Europe and America to step in will grow. The polish planes will be given, the free brigades will start getting armed in Romania and Poland, much like the Taliban were re-supplied in pakistan (by opposite sides over time too!).
Russia will then have a big decision to make, settle for the Eastern gains and have a Korea style ceasefire or go all out to crush Kyiv and the whole of Ukraine. Certainly the latter they are still aiming for today it seems.
For the West, what to do, a madman at the help of one of the largest Nuclear armed countries has bascially been our worst fear since the manhattan project. Lots of wars and efforts to try and stop this ever happening.
All the while, the economic damage will be great, whilst China and the East will benefit once more. In the grand strategy terms, this was is a total disaster for the US and Europe. For now we think it unites us, but there is no easy end and every day of fighting it strengthens an economically stronger competitor in China.
