BTW, I believe the “trigger” on an “H-Bomb” that gets the ball rolling is a built-in “A-Bomb” inside.

Yep.

The X-ray and gamma ray pulse from the primary compresses the secondary, initiating a fusion reaction, which amplifies the yield considerably.

And each single ICBM or SLBM holds about eight of those in a MIRV configuration, meaning eight separate targets (bases, ports, cities, industrial complexes or what have you) can be targeted and utterly destroyed, IIRC.
