It is well known that Stalin was in alliance with Hitler in 2nd World War. They divided Poland between themselves after capturing it. Stalin went against Hitler only when Hitler decided to gobble up Russia.It is only the tale of 2 criminals falling apart. The Indian communists opposed the British till 1942 and when Stalin came over to US side, they also switched the tone and opposed the Quit India Movement. Their stance is decided by their masters sitting in China as Russia is no longer communist. Now China is worried about the Nuclear agreement so the commies have been ordered to oppose it which they are doing as any faithful lapdog will do.
