That's my point, use a virus the has a higher mortality rate. Covid shut down this country with about a 9% rate. I'm guessing if this people have no problem strapping a suicide vest to they kids, then why not infect them. Guess I'm saying we need some type of boarder security or tracking. Just my opinion, maybe I've seen to many movies?A highly deadly virus wouldn't do much good.
It kills its self out too fast. Covid was effectively the perfect weapon for taking down a nation state.
