Russia and Ukraine

[Deesse23]

1. That was before NATO even existed ....

2. That conventional war not Nuclear weapons 

3. That was a US invention in a civil war not a first strike in a sovereign state 

So totally irrelevant 

Russia doesn't trust the West; they've been invaded several times over the last 200 years.  Now, maybe they should trust the West, but, at present, they don't.

...and thats your apologetics for invasion of Ukraine? History?
Germany has been invaded several times by France in the 17th-18th century. I guess the war of 1870/71 was aok then.

Back to Russia.
The most succesful invasion(s) of Russia were conducted by Poland, believe it or not. in the 1600s Moscow was taken and Russia had to accept territorial losses to Poland. In 1921 Poland attacked Russia and took parts of Ukraine, Belarus and Lithuania. 
Why does Putin not bother with Poland at all? He should trust Poland the least of all.

Yes, exactly, your argument is utter nonsense, historically.
