Is it not true that christian missionarys in other countrys are later followed by the military ?

Just like the mission system of California 15th century. The mission was soon followed by the presidio (military garrision). Churches in Cambodia are being destroyed by the native Buddhist followers. And now I see posts calling on all patriotic americans to fight back and save the churches.. Just Like the native americans, christianity and it culture are being forced uopn them because of some delusional belief by christians that they are saving them. Same justification for killing indians.
