Anil Bharali, It seems you have no clue about American democracy. They are far more focused with 2 party system. Their electro process is a fine example. Democratic party didnt split in the the name of Mrs. Clinton and Obama. They have their differences, but national interest comes first. In the Nuclear issue it is very clear politics played the role not the national the interest. WHO OWN. SURELY CHINA AND PAKISTAN. SO MANY COUNTRIES SIMILAR TREATY WITH THE US. NOTHING HAPPNED. NOTHING COWARDS RULING THE NATION WITH SELFISH INTEREST.
