It is now 4 years since Russia invaded Ukraine.
Originally most 'experts' thought Russia would have a quick victory and Ukraine would become a vassal state. This proved wrong and ukraine proved to be a formidable foe.They have proved to be both industrious and very flexible.
Since Russia invaded Ukraine then they began the hostilities. It is impossible to argue Ukraine began this fight.
An expanding NATO was never a problem either as it is, lome most treaties, a DEFENSIVE treaty. you can only call on other members if someone attacks your country.
Russia is not a great military power. Their tactics are poor and they do not appear to learn from any defeats. Their economy is in very bad shape thus Putin is conning everyone about peace talks. He has to gain a lot of territory politically.
It is interesting that Estonia recently wrote about Russia if Putin is deposed and it is worse than now!!
The western world should fully support Ukraine so it defeats Russia. Biden was way too timid and Trump is a Russian agent in acts if not in words.
No-one knows how much longer this war will last.
Postscript:
I should have added we as a nation should have given them out FA-18s. They are still okay, we are not using them and they are much easier to make airfields for!
