FWIW, Peter King acts like he cares about fighting terror, but was a prominent supporter of the IRA.
One could make the argument that the most significant difference, besides historical eras, between the Irish Revolutionaries and the American Revolutionaries was that the former were too close geographically to Great Britain and the latter has a French armada that actually showed up and won. After losing militarily, the IRA devolved from an Irish Army into civil war and terrorism, the same fate that awaited the American Revolutionaries had they lost militarily.
