Obama administration seems to be very happy by signing a nuclear deal with Iran.  Not knowing the full details of this agreement, still to be signed and approved by Congress, one hopes for the best outcome.  It is always a good idea to prevent the possibilities of war anywhere in the world, especially the Middle East Region.  However, the whole world knew the gist of this impending agreement - which has 10 years delay to manufacture any nuclear bomb and resistance on the part of Iran not to let the nuclear inspectors visit the military installations etc.  One wonders if those irritants - irritants especially to Israel - have been removed.  If not, one has to see the reaction and action on the part of Israel.  Prime Minister of Israel just made a remark that Israel will defend itself unilaterally, if need be, to save Israel.  I do not know what it means, but time will tell.  If that means Israel will attack the nuclear sites of Iran with their own arsenal, we are talking of symptoms of WWIII.  How about Saudi Arabia?  I am sure they are feeling perplexed, and must be knocking at the doors of Pakistan and North Korea to buy nuclear bombs to balance the power in the region.  No doubt a wide rift between Saudis and the USA and the latter's tilt towards Iran is making Saudis very uncomfortable.  Therefore, even though some type of nuclear has been signed with Iran, it is premature to say that everything in the Middle East is honky and dory and nothing to worry about.
