Do you have any solution that produces a result in a quantifiable amount of time?

I'm going to set aside the fact that it is impossible to guarantee a timeframe on anything, and assume you meant "realistic suggestions to end the war".

But, oh you won't like my suggestions one little bit and we have proof from the thread to date you won't actually engage with them, you'll just dismiss them.

So, the minimal effort response is - Russia has already been ground to a halt - they've not been advancing in any significant way for at least 2months. What makes you think Russia can win from here ? They can't get fuel into Crimea where they've been staging attacks from, they can't get supplies into their troops on the frontline in many areas, and on the home front there's plenty of footage of farmers going broke for various reasons and not being able to produce. Famines are always great for home-front morale so that contributes to one of the options you ignored. Troops without supplies and ammo can't fight and will have to withdraw that contributes to another.

TL;DR more money and supplies to Ukraine, much more than we are currently supplying. They're doing a great job of making it difficult for Russia to continue.
