You can look at it the other way. Putin took the Crimea. Putin promoted the break-away republics. Without him, they would not have happened.
In all the similar cases, the common theme is Putin. He did the same to Georgia as he is to Ukraine. He did the same to Moldova, with Trans-Dniestr.
Were all those governments also reckless? Or were they just unfortunate enough to border Russia?
Putin has been consistently threatening to the Baltic states too. He even sponsored cyber attacks on Estonia. Now it is a long bow to draw that they have been reckless.
No. Putin is the common theme. Nothing Ukraine did, short of bowing to his every wish, would have stopped him. They have not been reckless. They have been desperately trying to deal with a homicidal maniac over the border.
Your argument reminds me of telling battered spouses that they should be more careful, rather than pointing the finger at the violent thug doing the violent things.
