I think the response to this is simple, because it's the same solution that it's always been: revolutions happen in local spaces with people who are together in person.

you’re probably facing the US military in addition to the militaries of all its allies

Likely not, as Lenin says,

"The fundamental law of revolution, which has been confirmed by all revolutions, and particularly by all three Russian revolutions in the twentieth century, is as follow: it is not enough for revolution that the exploited and oppressed masses should understand the impossibility of living in the old way and demand changes; it is essential for revolution that the exploiters should not be able to live and rule in the old way. Only when the 'lower classes' do not want the old way, and when the 'upper classes' cannot carry on in the old way, -only then can revolution triumph. This truth may be expressed in other words: revolution is impossible without a nation-wide crisis (affecting both the exploited and the exploiters) .10 It follows that for revolution it is essential, first, that a majority of the workers (or at least a majority of the class conscious, thinking, politically active workers) should fully understand that revolution is necessary and be ready to sacrifice their lives for it; secondly, that the ruling classes should be passing through a governmental crisis, which draws even the most backward masses into politics ... weakens the government and makes it possible for the revolutionaries to overthrow it rapidly"
