Without a doubt the resistance the Ukrainian army and their civilians are exercising have surprised the Russian army and even the allies of Ukraine, but in an attrition war Russia has the upper hand despite the sanctions which have been raised against it, for the simple reason that all the battles are taking place at Ukrainian soil which means the Ukrainian are the ones paying the higher price from the war.
It is true - Ukraine has very modern weapons which are destroying the Russian tanks. Russians too are unable to realise where their technology have failed.
I am unable to realize how the authorities allow the war - and see their people dying.
