PROBLEM: Washington (CNN) George W. Bush tried it. Barack Obama and Hillary Clinton tried it. Now Donald Trump is vowing to reset relations with Russia. But could the unintended costs outweigh the benefits? The President-elect's Russian gambit seems like a solid foreign policy goal, given that the estrangement between the rivals -- owners of the world's biggest nuclear arsenals -- is deeper than at any time since the Cold War. An improvement in relations could yield gains for the United States in reviving non-proliferation projects and closer anti-terrorism cooperation. But there are big questions about whether Trump will be any more successful than his predecessors, whose initial inroads eventually foundered largely due to the behavior of President Vladimir Putin, and whether he will end up emboldening a leader that many -- including key Republicans in Congress -- see as a top US adversary.Closer US-Russia ties could revive non-proliferation projects and closer anti-terrorism cooperationBut closer ties could also mean restoring Russian influence at the direct expense of the US 
 Question:Trump has made no secret of his admiration for the Russian strongman, once saying he was a better leader than Obama, and on the campaign trail showed little concern about resurgent _ influence.

SOLUTION: Russia

PROBLEM: (CNN) -- Each year, more than 3 million Muslims commit to Hajj, the pilgrimage to Mecca that represents the fifth and final "pillar" of Islam and the largest annual human gathering on the planet. Every Muslim who is physically and financially able to do so is expected to make this pilgrimage once in their lifetime. As described in the Hadith of Gabriel, each pillar of Islam acts as a guide to day-to-day conduct for Muslims, outlining proper professions to God, prayer and spiritual mindfulness, not unlike the Book of Common Prayer for Anglicans or Judaism's Siddur. For this year's Hajj, iReporters from around the world documented their journeys, describing their experiences as they complete this Islamic sacrament. Thanks to the power of social media and platforms like CNN's iReport, they've been able to share their faith with the world, giving Muslims and non-Muslims alike a glimpse of the significance of this powerful and transformative event.More young Muslims embarking on Islamic pilgrimage than ever before2011 Hajj could be a flashpoint for global Islamic revivalPilgrimage is a defining moment in the life of MuslimsFollow iReporters as they complete their Hajj
