You seem to be caterwauling the same tune over and over again trying to convince us that we should send in troops because that's where a NFZ will eventually lead. NATO is giving them far more effective weapons and logistically it's getting down to even the civilian troops. Russia has lost a significant number of men and equipment which cannot be sustained. Their logistics are a nightmare and will not be getting better. Be patient
When we are getting Javelins, suicide drones, and more down to the civilians fighting then our supply lines are flowing freely.
Another thing you've been upset about is that Putin is calling for others to join the fight. Russia has a large force that can be conscripted (900,000) why isn't he doing that? Because rumor has it there would be a revolt as many in his regular army don't want this war. He's arresting his own staff and the longer this war goes on strategically it is better for the world (not so much for Ukraine in the short term) because Russia will be crippled economically as well as militarily.
Silence is golden but duck tape is gray.
