@Alexandra2001 There can be no peace while Russia continues to occupy any part of Ukraine. They will cynically use any ceasefire or peace deal as an opportunity to rearm, rebuild their armed forces, and come back for more.
The way to end the war faster is to send more equipment and ammunition to Ukraine, not less. More air defence to protect Ukrainian cities and infrastructure, and more artillery systems and ammunition to repel Russian frontline attacks.
Russia does not actually have huge resources. What it did have was a huge legacy of Soviet era equipment (i.e. manufactured pre-1991, 33+ years ago). Much of this is now smouldering scrap metal in Ukraine, to the point where Russia is sending men into battle on Chinese-made golf buggies instead of armoured vehicles.
Just look at the Russian 'Victory Day' parade yesterday. They had ONE tank... a WW2 era T34. Not exactly a showcase of military might. If Russia were a military superpower, it wouldn't be using human wave assaults of convicts and ethnic minorities as its primary method of attack (actually it probably would, because it's Russia and that's what they do).
It would also help if the West enforced sanctions properly, instead of allowing exports of critical components to Kazakhstan etc that just get re-exported to Russia.
Russia keeps talking up the nuclear threat because it's all they've got. The reality is that they aren't going to use nukes over the war in Ukraine, and we shouldn't allow ourselves to be intimidated by their empty rhetoric.
