there are many guesses that the most possible war the US will like to carry out is operation against Iran, the reasons are given as follows: first, Iran is the only hostile nation left after 2011, the second, Obama may need more votes for his presidential election, the last but not least, the oil, the energy most developed countries eager to want. Now the Hormuz Strait attracts lots of attention from all over the world, there, Iran want to show his power and strength, and may irritate the Western led by USA. Let us hope the best that no war at all in the year 2011.
