2. Robert Levinson - A "retired" DEA and FBI agent, Levinson was taken hostage on March 9, 2007 on Iran's Kish Island. Note how until recently, the US has described him as a "private investigator". On December 12, 2013, the AP confirmed that he was working for the CIA. So the US's new story is that he was "on an unapproved mission". Yeah right. The United States has since reached political agreements with Iran without, in so far as known, even attempting to condition those agreements on Levinson's release. A shocking betrayal.
3. Alan Gross - In December of 2009, Alan Gross was arrested while in Cuba working as a USAID "private" subcontractor. He was/is still in a Cuban jail as president Obama smilingly shook the hand of Cuba's President, Raul Castro, at the funeral for Nelson Mandela in South Africa. Gross is scheduled for release in 2024.
