That's a straw man argument.
Heck, if you play that game, the U.S. could then turn around and make all Jamaican citizens, U.S. citizens. If such a thing were viable, it would have been done long ago, and the actions would have stood the test of time (See War of 1812).
Such a move would not be internationally recognized and therefore would be unenforceable, even inside Jamaica, which would find itself internationally isolated (in the very least) if it did try to enforce such action.

Which us why talking about dual citizenship per se is useless. My “straw dog” is far fetched but many citizens of the USA could just walk into a passport office of their parents’ country of origin and become citizens. If that country wished to cause trouble, it could just issue the citizenship unilaterally. Dual citizenship is a non issue as long as there is no evidence of loyalty.
