ANKARA/ISTANBUL - When Washington takes its bombing campaign against Islamic State fighters into Syria, the most it can probably hope for from one of its closest allies in the region will be grudging consent.
Turkey, a NATO member with a big US airbase and long borders with both Iraq and Syria, has made clear that it is still unconvinced by US President Barack Obama's plans to bomb Islamic State fighters in two of its neighbors.
While Washington won backing last week for a military coalition from 10 Arab nations - Egypt, Iraq, Jordan, Lebanon and six Gulf states including rich rivals Saudi Arabia and Qatar - Turkey attended the talks but did not sign up.
