donald trump is more comfortable celebrating with the saudis than he might look. that's beautiful. it's certainly more comfortable for him here than it is back home, given the furore over his sacking of the fbi director investigating allegations his presidential campaign was tied to russia. but day two of this tour could be the beginning of a far greater challenge as he leaves the world of striking commercial deals he knows so well to try to strike political deals instead. one of his goals is to eventually do what no other experienced leader has managed and bring peace to the middle east. and this is the president who tried to ban visitors from six mainly muslim nations. but the amount of red carpet they've rolled out for him here tells a different story. his tough stance on iran has won him many friends in saudi arabia. always the right hand, right? always the right hand. if only teacup diplomacy were enough in a region where some disputes stretch back thousands of years. supporters believe donald trump has got his own long history
