This is an old debate with the Godmodding, but always a thin line to walk.
I have issues with anyone claiming they have evacuated civilians from a sovereign planetary government. I'm pretty sure local Holders would be less than helpful to foreigners coming in and taking their citizens, be they nation or other random capsuleers.
Our version (successful or not), was to simply supply forces in advance that I could basically prove in-game, and not speak on the outcome, leaving that to the actors present, etc if they chose to. We made very clear effort to state we gave up all control of those units to the local authorities, etc and that we were not running the show when they were on the surface. Capsuleers have no authority on planets aside from their own land, etc, which you can always make a case for. Perhaps sending troops to your own planetary structures can be backed up, but I don't see much else aside from that.
I just don't see any way to rationalize IC, say, a KPV freighter running into minmatar space and 'helping' the locals by taking a bunch of civilians and dropping troops during a fight. They'd be shot out of orbit immediately, I would imagine.
I'm sure opinions are varied on this, but a tough line to walk
