Yes, but where does the US launch them? China can launch a swarm of these from the Pacific and guarantee they'll overfly the US and Canada due to the jetstream. Where can the US military launch a counterswarm that won't have to overfly a bunch of other countries with unaligned military strategies? All that does is create a negative diplomatic situation with those countries, and they'll likely shoot them down before they reach China.
