Do you know kavitha, how many times Congress has pulled out of the central govt? Deve Gowada, Gujaral, V P Singh, and of course the corrupting the Desai's govt pulled it down. Supported other govt headed by some south indian guy, i forgot the name, and then pulling support to him too. And vajpayee's govt - defeated by 1 vote.
This is just politics - and nothing else. You can not blame left - they did tell PM that they will pull the plug - that's why he waited for 4 long years - so that he can screw the country for 4 years, now that the election has to take place this year, he wants a sorry face to go to people - and that is the reason for this whole stunt.
do not blame left for this, although i am a darn opposed to left and supporter of Bjp - i would say that in this case Congress is more responsible then Left. What left did was not news to PM - if he undermined them - then it is his foolishness.
Whatever the case may be, left has pulled and now he is in minority, he can not do any big international treaty. Period. It is unconstitutional.
