Judging by your name, you live in New York City. I get it that domestic terrorism will now be exacerbated, but I'm not sure I would leave home because of it. In any case, enjoy beautiful Costa Rica. The rain forests there are so beautiful and the air is so pure. Safe travels!
I spend time with relatives in the Nitra Valley of Slovakia. My immediate family is boarding up their home waiting for me in Kansas. We are going to Costa Rica and here is why.
IMHO the Panama Canal would not be on any nuclear capable nation states strategic target. It's cross ocean route is too valuable lest nuclear adversaries care to waste valuable time and fuel steaming around Cape Horn. Also keep in mind that In the event of a global nuclear conflict I pray for the multinational scientific community on Antarctica because how will they survive?
