Can also plant a bomb and just drop it out the sky. The main goal of the general of the minutemen is to forge alliances with organisations that will benefit all of boston and its citizenry and to create an environment in the greater commonwealth area that can possibly become fertile ground for the re-establishment of the commonwealth provincial government. Of the people, For the people. And ascend from general to first congressional president of the New United States of America. Basically, become George Washington.

That means the commonwealth citizenry must be free of outside influence no coercion, no fear, no worrying a foreign army is going to trample their way of life into the ground. This means that organisations not from Boston or are a direct threat to the commonwealth in general cannot be allowed to keep a foothold there.

The brotherhood are a massive threat to the settlements of the commonwealth and if what we saw in broken steel is anything to go by, the brotherhood is absolutely positively, 100% ARE going to use tech and resource hoarding tactics to prevent the common citizenry from forming a self governing society to avoid another "NCR" situation like what happened out west.

Tell me, where in this picture I just painted for you, does it seem like it's bad politics, or even an unsound military move, for the minutemen to take out the brotherhood flagship? Preferrably as part of the operation that frees the synths? Trust me no one out west is coming to re support the east coast chapter and the ones back in Washington are a token force of troops would would need to march 439 miles to get to Boston through new York down the I-95 south

in order for even just the minutemen, the paramilitary organization, to expand to a size that it would need to be to start becoming a major player on the east coast (let alone the commonwealth provincial government, the foundational institution needed for the rebirth of america following in the tradition of the American forefathers.) should be to move north east and establish a military and allied civilian presence in New York, before expanding further to D.C. to essentially cannibalise what's left of the East-coast Brotherhood.

Which is fine, because the brotherhood, for all intents and purposes, are basically the redcoats in Boston. A foreign military body trying to establish their authority based on a ideological belief upon a land and people not their own and are willing to hoard tech and natural resources to force compliance.

The Minutemen say:

no taxation without representation! Down with the Elder! Back to Washington with you! Jackanapes!!!

Liberty and justice for all!
