I tuned in after it began but did catch the part about the efficacy of embargoes. The rapidity with which it is put in place and the extent of it. Support from other, adjacent nation-states. In Haiti, the embargo is compromised by trade with the Dominican Republic 3. Haiti is weak and without powerful allies.
Embargoes are effective with allies and trading partners.
The rich and powerful have first call on scarce supplies. This is true in Haiti, Iran, and other countries where embargoes have been instituted. Those who are concerned about Cuba might want to consider the implications of this study. Much of the present distress in Cuba comes after the collapse of Soviet support. End of this posting.
