So we should simply have ceded the Baltic states to Russia? Is that what you are suggesting?

No, I am not suggesting this. And to my knowledge neither did Russia at any point suggest this. If Russia did, kindly share. The probability that Russia will invade Europe is propaganda propagated by western media. Request you to watch the 2 videos I have linked above.

But that is what you are insinuating about Ukraine. We should not have let the Ukrainian people self determine their path and instead given them the cold shoulder and left them to Russia.

You are, in fact, either suggesting that or are entirely unaware that Ukraine had a peaceful agreement with Russia prior. The entire point of giving Ukraine official sovereignty was to reduce international pressure on Russia - everyone knew that reneging it would bring war to Russia's doorstep, it's written in black and white on the Budapest memorandum.

You can blame Russia for not knowing their worth, but they did break the treaty and there is no rational justification for doing so.
