This statement from another thread tells you where the battlefield will be.
” Clinton carried Manhattan and Brooklyn by approximately 1 million ballots—more than Donald Trump’s margins of victory in the states of Florida, Arizona, Georgia, North Carolina, Michigan, Wisconsin, and Pennsylvania combined.”
Food and transport lines will be the weapon, along with disease.
We should all consider EMT training.
And Clinton carried Kalifornia by an even greater margin... what a waste of humanity, or carbon based units endeavor.
Manhattan is an island, and produces NO food or other sustainables. Block access to and egress from the island, and it will consume itself in short order.
