“Biden’s expertise in foreign policy, national security, and arms control issues has won him considerable bipartisan respect. In 1997, he became the ranking minority member of the Senate Committee on Foreign Relations and chaired the committee from June 2001 through 2003. His efforts to combat hostilities in the Balkans in the 1990s brought national attention and influenced presidential policy: traveling repeatedly to the region, he made one meeting famous by calling Serbian leader Slobodan Milosevic a “war criminal.” He consistently argued for lifting the arms embargo, training Bosnian Muslims, investigating war crimes and administering NATO air strikes. Biden’s subsequent “lift and strike” resolution was instrumental in convincing President Bill Clinton to use military force in the face of systematic human rights violations.”

He obviously has no experience of the region and no reason to go there, especially considering the fact that hostilities could flare up again.
