The United States should rally other Latin American leaders to condemn human rights violations in Venezuela.

We can aggressively hold individual political and military figures responsible for promoting violence, condoning or committing human rights violations.

the Maduro government would clearly love to turn their domestic crisis into a bilateral one, and we should not be sucked into that dynamic

Oil sanctions by the U.S. Government would be a reward for the Caracas Government and its Cuban partners.

Failure to do it will be an abdication of U.S. values and principles.

The future of Venezuela belongs to the people of Venezuela. They must determine the direction of that country and what sort of system of government and economics they want.

The defining issue of current-day Venezuela is the wholesale, state-sanctioned, and amply documented violation of human rights of those who oppose the government.

The United States will not stand by an idly watch as the rights of people, with whom we share this hemisphere, are systematically violated by an anti-American government.

After 15 years in power the government owns this crisis. They made it and it is theirs.

I strongly support doing what we can to help Ukraine, the interim government, civil society and soon a newly elected leadership, but helping Ukraine requires simultaneously pushing back firmly against Putin and his regime.

In my view, President Obama's decision to impose sanctions and send hundreds of U.S. troops to our easternmost NATO allies is a correct response.

Russia's actions stand as an affront to the international order that we and our allies have worked to build since the end of the cold war.
