Earlier this week, the United States had a congressional committee hearing wherein the discussions of Iran trying to spread influence in Latin America was discussed.
Lately, Iran has been in the news because of the talks of potentially creating its own nuclear program. This has come with lots of dissension, and some may believe Iran is trying to gain support in Latin America towards this program.
If Iran establishes solid ties with a Latin American nation, it could pose a threat to U.S. Interests because of its presence in the Western Hemisphere.
