The statement that explains why Roosevelt offered U.S. naval support to Panamanian rebels fighting for independence from Colombia is <em>The Colombian government would not allow the United States to have control over the Panama Canal Zone</em>. The United States helped Panama declare independence from Colombia, then negotiated for the canal. On November 3, 1903, Panama with United States Navy support revolted against Colombia and became a new republic. The U.S. gained the rights in perpetuity to the canal strip.
