I cannot condone violence to the people of Ukraine but the diplomacy here has been handled appallingly. Everyone knew that sanctions wouldn't work. Johnson's relationship with Russian oligarch families. We are in the hands of total incompetence.
Russia has just signed a 117bn energy deal with china, in early Feb of this year. This crisis started when China leased land in Ukraine 2013 there is thought to be a link there. China and Russia are not going to be at all discouraged by sanctions.
Both China and Russia have said they want diplomacy and negotiation and I think that the West proposing to negotiate over NATO in Ukraine is our only chance. You have Russians vs Ukrainians in these territories, it is and has been for a while akin to a civil war, and the focus should be on that not seeing this as just saving Ukraine.
I don't think Putin will stop unless the West stops the sanctions and asks for genuine discussion. It is a risk of course, in fairness the Ukrainian government has made moves recently in relation to its internal dispute. But I think that sanctions and threats is more of a risk.
