The German intelligence official reportedly mediating a prisoner exchange to bring home Israeli soldier Gilad Shalit had previous success with an Israel-Hezbollah swap in 2008.
Palestinian polls show Abbas gaining significant support in recent months over Hamas, which harshly criticized his willingness to meet the Israeli leader without a settlement freeze in place.
A majority of Israelis support a two-state solution, including steps such as a settlement freeze.
A consensus to isolate the group is fraying due to the lack of political results.
