There are airports, ammo depots and other facilities less than 100 km from Ukrainian cities, and Russians are safe(mostly) there.
While at the same time Russians every day continuing their terrorist attacks on Ukrainian cities.
Russia is a terrorist state, but world doesn't care if they can have profits from Russia.
But after this summer of letting the Ukrainians flounder along the front in a stalemated counteroffensive, I am frustrated. The F16s should have been there this summer.
And now Avdiivka will become this winter's Bakhmut and the US could very well end up with a Putin-allied Trumpler in the Whitehouse next year.
Unfortunately for Ukraine, there is no powerful politician like Reagan nowadays.
Hard times create strong men. Strong men create good times. Good times create weak men. And, weak men create hard times.
We had decades of peace and prosperity and now hard times are coming.
If you think that west should give up and let Russians win and keep occupied territories - you should learn European history better.
Remember "peace for out time" agreement with Hitler in Munich 1938?
Likely if the west provided jets, this would change drastically.
I actually agree Russia is not stupid enough to engage in a direct attack on a NATO nation. They would likely move next against in Transnistria, Georgia, etc. And I don't see what would stop them, if they have success in Ukraine.
But they will engage in hybrid warfare against the west (already were), and they will be twice as emboldened if they are given Ukraine.
This is a country that felt free to unleash radioactive poisons against persons on UK soil, shoot down a civilian airliner, etc. Why do you want to appease them?
