The cyclone that stuck Myanmar (Burma) was a devastating one. It caused huge material damage, lot of life loss, and millions of people were displaced and without place to live because their homes got destroyed. It has been a full scale humanitarian disaster.
The United States were among the first countries to offer their help, both in goods and financial aid. This was not accepted by the government of Myanmar though. The government of this country has been keeping the country isolated from the world from quite some time, and despite the disaster it planned on continuing so and rejecting the aid.
The United States then appealed in the UN council in order to make a bigger pressure on the Myanmar government, so that it backs off and allows the foreign aid. The pressure was put upon the government of Myanmar, and eventually it softened its attitude and allowed for the United States and other countries to help the people. This was all done with assistance and constant military presence, but at least the United States managed to help the people of Myanmar with the pressure it put upon the government.
