I mean that's a large part of it yes. The main security threat is USA and NATO having nukes on the border ok Ukraine. Would be like Russia putting nukes in Mexico for a somewhat close comparison. But a lot of the conflict started in 2014 with the organization NED the National Endowment for Democracy. If you look up NED, look up their directors. CIA ran. Yet a non-governmental agency.. They basically say they are for democracy but then run regime changes.
