'Released from foreign war, we would probably be plunged into all the misery of anarchy and intestine war. Can we suppose that the people of the south, would submit to having the seat of Empire at Philadelphia, or New England; or that the people oppressed by a change of government, contrasting their misery with their former happy state, would not invite Britain to reassume the sovereignty.” — James Chalmers, Plain Truth, 1776
If the one above is the argument, you might consider that the colonists did obtain independence from England. That by itself was something that Chalmers always thought to be impossible without serious repercussions. He used to say that in the case of achieving freedom, America would just end up being attacked and maybe even colonized by some other country. What happened, thought, was that after the revolution, other countries gained respect for America as an opponent and the country was eventually left to be.
Well from the way I see it, if other countries were to get in on the holocaust it would just make it worse becuase then Germany would have to start a war with those countries and it would be a big mess and I’m sure other countries feared that something like that would possibly happen which is why they didn’t act upon it and if they did they would be causing problems for their own country which is what they didn’t need.
