There was another video on the same vein posted where the guy was making that kind of insinuation.

I don't have any solid answers, but in this instance it does appear more a mundane explanation. The early claims of flooding the tunnels was explained as requiring diverting the Potomac. Seems that would be the scale of action required.

Btw- thanks for clarifying, you weren't coming across as shilly, as much as someone who was effectively normie until the past few weeks. I see your point and no real offense was intended either way.
