Several years ago, I read an article about a Russian historian who predicted the balkanization of the United States. Now, a Russian-supported US President appears to be driving the country toward that end result. Do you think Trump's fight against santuary cities/states will lead to this?
I wonder, if Trump ceases payments to some of these states, would states like California that are net donors fight back by suspending payments to the federal government? Would Trump relent, or send in the FBI, US Marshals, or federalize the state's guards to force the state's governor and legislators out of office? Would those states, especially those with access to the Sea, declare themselves independent?
I've seen articles about Canadians inviting the west coast states to join them. Some of the blue-ish Midwest states might feel stuck, but if they joined with Canada to some extent, then the Great Lakes states would be able to get out to sea via the St. Lawrence if all the Lake bordering states join or honor transit treaties.
I wonder how the south and plains would react. With the net loss of federal income, they would receive less funds, which might make them angry at Trump. Or they might not blame him, because Cognitive Dissonance. The long shape of Illinois provides a natural blockade that could starve the northern Plains if people don't want to drive all around to bring food, but since they have oil to trade, they might hold on. However, flight of industry because of economic realignments from the low population plains might shrink them to insignificance.
What do you think the map may look like?
