They don't fly sun synchronous orbits, so a giant vertical laser cannon near equator running 24/7 can kill them all in matters of days. I think. Carrying this out likely also constitute a de facto declaration of war against the US.

Why near the equator? How much energy do you think it'd take to destroy one, over what period of time. Do you think you can aim your laser at something the size of a desk moving 8km/s at 500km-1500km away?
