Yes, the last bomb in your video seem to have the highest altitude or most feet. The question is, would they actually choose to ever use it? I dont think so. General Powel told them what we require and hoped they would adjust.

No one really needs a more powerful nuke.......collectively, we have way more than we will ever need!

To any NEW state that wants to develope a nuclear weapon, we should first ask them why they want everyone in the world DEAD and BURNED.

They want to control by fear.
