Obviously, there are alternative explanations for both periods such as WW1 for the first period and the Arab oil embargoes for the second.  

The event will now be hosted at Embargo on Main St.

I’ve been around long enough to recall the 79 opec embargo, 87 crash, y2k, twin towers going down, the housing crash in 07-8, and other crashes.

Cuba could be an upside bet if Obama finally kills the trade embargo. in all of these countries, go into urban areas.

We had gone thru the oil embargo,etc.

Absolutely, foriegn individuals and entities may hold title to US property, if they are not on the embargo list with the State Department as to transacting business.

The second that alliance falls through for them, we dump due to the same reasons we always did, political differences, embargos go back up, and so do the travel restrictions.Its hard to collect rent from a country that another country hates, and good luck enforcing your ownership rights in the event of a dispute.

I totally agree about Airbnb saturation, and with Tripadvisors'/Flipkey's massive customer service issues on both the renter and owner side, not having a solid property management company in place could be devastating.That being said, nothing can replace natural beauty, ease of travel to and from is incredibly easy from anywhere on the east coast, so the allure will remain.One thing I will say that would most certainly and quite seriously hamper tourism in PR, and pretty much most of the Caribbean, a lifted embargo with Cuba.

During the major campaign to force Iran from building a nuclear facility capable of enriching uranium, we placed a financial embargo on them.HSBC was caught moving money for Iran at a steep markup of 5-8%.The total moved money ranged in the billions.US government fined them a few million dollars in penalties.

If nation states like the US and the European Union embargo Russian fuel, guess what happens?
