Because Russia broke them on the first week, yes.
>EU ignored Crimea annexation and continued pumping billions of dollars into Russia (you can see these billions now in form of rockets and bombs in Ukraine)
How is that western/NATO aggression ?
>NATO has been expanding to the East and antagonising paranoid Russia.
NATO is not an entity that looks to engulf everything. Countries see themselves next to Russia, see the bullshit that happens when Russia doesn't honor its agreements with the CSTO members (Amernia and Azerbaijain duking it out make everyone realize how much of a joke the CSTO is), and decide to join NATO. There is no "NATO expansion", there is no agreement of not letting new countries join either. Noone is forced at gunpoint to join NATO.
