IRAN ISSUE

Recently their has been news that Indian company O.V.L which has gas exploration and extraction agreement with Iran has been having 2nd thoughts.
Due to increase in U.S and E.U sanctions foreign companies are having difficulties in dealing with Iran.O.V.L has asked for legal and diplomatic opinions with other government departments over the issue.
So my point is O.V.L has to walk-out of Iran gas deal because i don't believe Indian government is going to ask American government to give a waiver only to Indian company.Given the nature of American and Iranian government relationship the American government will do any thing to make Iran craw under its knees.Iranian nuclear issue is only a picking point the American government has taken.The real issue is Iran has large reserves of oil and gas and the government in not on a friendly terms with America.
The reason American government has not attacked Iran over nuclear issue is - 1st Iran has not "yet" processed uranium for weapons and 2nd straits of Hormuz which can be blocked by Iranian even for small time which might cause disruption not halting of all tanker flow and 3rd alternate pipeline through saudi Arabia to Jordan to Israeli port of Haifa is not ready and other form Kurdistan through Syria and Lebanon Beirut is also is not ready.
So my belief is the American government will attack Iran when these pipelines are ready and when they are completely sure of Iranian nuclear program mature enough to produce nuclear weapons which they not yet have.
so what you guys think.
