He didn't wait 30 years.
Putin has only been in power since 1999
Since then, Putin put down a separatist movements in Chechnya.
He invaded Georgia in 2008.
He invaded Crimea in 2014.
He invaded Ukraine in 2022.
He solidified his hegemony over the vassal state Belarus during the last two decades.
And he used the last 20 years to rebuild a dysfunctional and decrepit Russian military into world class capabilities, and capable of projecting power..
What on God's green earth made you assume Putin has been sitting on his hands for 30 years??
sorry I was thinking of USSR -30 years. Georgia and Check are small affairs
If he wanted Ukraine he would have gone after Ukraine long before now.
Putin did try diplomacy -more then Biden ever did ( Trump could not) and Obama tried diplomacy
If Ukraine was the big get, he certainly would not have waited almost 25 years.
So why now>because everything changed as a result of the Maidan.
Ukraine kicked out a president who tried to be neutral, Kyiv became belligerent to the east
not even offering autonomy. that's why the Separatist war broke out.
Trump impeachment was a clue -look at the testimony by Vindman and Fiona Hill -they supported impeaching Trump simply because he held back on weapons pending getting Zelensky to look at Biden's crooked arrangement. There was no war with Russia then -but even temporary delays got their panties in a bunch. They wanted Ukraine to militarize and become a proxy NATO state NOW.
Unconditional weapons flows
Russia sees all this, sees Ukraine becoming a hostile western dominated state -
the proximate cause for the invasion -not some speech from 2005
