Pretty much. But that's what the people in Donbas wanted too.
It wasn't, watch this series, especially episodes 8 and 9. It was completely coordinated by Russia.

It was their election mandate that was stolen in the 2013 coup.
Nope it was the other side's election mandate that was stolen by Yanukovych when he joined the EEU instead of the EU. His exact words in the 2010 campaign when he was elected (episode 9 of above series):
"Our priorities includes
integration into the EU and a friendly and cooperative relationship with Russia." Putin blackmailed and bribed him away from that.
Believe it or not Medvedev was a reformer between 2008 and 20012 too. He went about exposing corruption, but that was pointing fingers at Putin, hence the huge protests in Russia in late 2011 and early 2012, when Putin stole Russia. Medvedev was then subjugated and became a drunk parrot.
Russia President Dmitry Medvedev has ordered an investigation into allegations that a top Kremlin official took huge bribes in connection with the 2014 Sochi Olympics. Analysts are unsure whether it's a sincere crackdown.

You're on the wrong side.
It's like if the EU attacked the UK for the sake of stopping Brexit.
Which they didn't, so what's your point?
They have claimed it, but haven't yet provided proof, ie, images and videos of these attackers under the ISIS flag, or being given a sermon or peptalk by a known ISIS leader.
ISIS has a habit of claiming attacks they didn't do, like the attack on the gay bar in Orlando. Their logic is if a Muslim man attacked infidels, then it's the work of ISIS, as long as someone else didn't claim the attack with proof. It helps them recruit more.
So now them claiming it is no longer enough huh?

FSB likely funded the attack anyway, Putin wants to declare a full mobilisation and this attack only serves his interests. Ukraine is killing 8-10x as many Russian troops every day and taking out Russian oil and gas infrastructure and major military assets. This concert attack is insignificant and meaningless in terms of the Ukraine War, they would not waste resources on it.
There's a whole shitload you don't know about Putin, so stop pretending he's a saint, it just makes you look dumb. And also stop pretending you know anything about matters in Europe, which includes the European section of Russia.
