US Defense Secretary Robert Gates said Tuesday that there is "no grand bargain" with Iran as the US tries to bolster relations with the Teheran government. Asked by reporters what kind of progress the US was hoping for with Iran, Gates said he did not know what was possible. Gates met with Egyptian President Hosni Mubarak Tuesday morning. Later, he is flying to Riyadh, Saudi Arabia. He said he would rely on Saudi Arabia to help with the situation in Pakistan, where violence has been building as the Taliban advances toward the capital Gates said the Saudis "clearly have a lot of influence in the entire region."
