We've been to jail, we've marched on Washington; this week it's pixels and keystrokes. This electronic blitz is an effort to show Congress that there's support out there for doing the right thing.

Judge Garzon has courageously sought accountability for atrocities around the world. His conviction in the wake of his pursuit of justice for the murdered and the disappeared should be a warning to all who care about human rights.

Argentina's foreign minister wants the United Nations to mediate with Britain over the Falkland Islands (Malvinas) and accused London of militarizing the south Atlantic. "Rubbish," responded Britain's ambassador.

Iranian lawmakers this week expressed support for a measure that would beat the EU to the punch by cutting off oil exports before the summer. This amounts to a statement of economic warfare

It is lack of political courage that has permitted this looming confrontation. Only courage and will can bring us out of it. The question is whether Obama can muster that will in an election year when any compromise is bound to be cast by Republicans as a betrayal of Israel.

Fact-checking sites, pundits and politicians failed to deal with the issue. And despite the AP story, no major American journalist, columnist, debater or think tank has demanded that Gingrich apologize for this brazen lie.

The politics of the Eurozone are evolving. As progressive and conservative visions for the continent's economic future emerge, unprecedented levels of cross-border political co-operation are now also taking place.

When a nation's rule of law has broken down completely, the international community needs to know exactly how and when to step in to prevent human rights violations from occurring. The ongoing conflict in Syria has pointed out just how far we are from truly fulfilling our Responsibility to Protect.

Instead of following predictable (and boring) scripts, why not turn the page on Cold War-esque rhetoric and find ways to join hands with China so as to mutually benefit from each other's comparative advantages?

I go to India at least once a year to see the progress of the work our foundation is doing there and I'm always struck by two things -- the dynamism of the place, and the tremendous need. Unfortunately, the former doesn't cancel the latter out.

This indeed is the most important card Putin holds: the fact that Obama will not go to war in Syria, that he will not go to war in Iran, and that it is out of the question for him to escalate against Russia or China -- he, the advocate of peace.

Panama is in the midst of one of its most serious political crises since the return of democracy in 1989. Clashes in recent days are part of a broader climate of political turmoil stemming from the growing authoritarianism of president Ricardo Martinelli.

Executive director, Global Centre for the Responsibility to Protect

Last weekend's double veto should have put a nail in the coffin of the idea that Russian opposition to UN Security Council action in Syria was about post-Libya fallout and the "Responsibility to Protect." The veto was about arms, allies and power. Nothing more, nothing less.

Hamza Kashgari fled Saudi Arabia to Malaysia on February 7, 2012, after a storm of outrage erupted over a fictitious conversation between him and the Prophet Muhammad that Kashgari published on his Twitter account.

Last week a UK minister created an economic myth about immigration to his country, and it's useful to watch how and why it arose.

Almost exactly 100 years ago President Theodore Roosevelt spoke to the General Assembly of Cairo University. Egypt was then, as it is today, in political turmoil.
