Roosevelt Corollary 1904
This corollary was to the Monroe Doctrine (1823). Venezuela wasn't paying their debt. Germany is getting tough with them. The corollary says Latin America nations must pay their debts, if they don't the U.S. would reluctantly police you, collect the debt payments in order to stop European internevtions. This is quickly testes in the DR, we sent marines and start collecting their import taxes, 45% goes to DR 55% will go to pay off debt.
