bro you seem like a nice guy but that's nonsense, you must be very young. a humanitarian mission can't occupy shit and if russian troops appeared in their area they can't shoot at russians or tell them to gtfo, un troops in bosnia for example were just sitting around while this and that army moved in or left. therefore they can't prevent the occupation. if they engage in a fight, they would have to hold that territory but russians would just bomb them and 100 casualties would be a disaster for eu so they'd just back out. if they are retarded enough to go in it will be a short expedition and very costly in human lives.
