In diplomacy you do not trust anyone blindly. You have to see what is the best for your own nation. Many US Presidents & Chinese Communist Party Chiefs or Russian Presidents will go back on their word, not to loose their credibility but to save their nation if they feel the time has come to do so. They will keep personal image, vendetta or party politics aside and act. Let us not be foolhardy to do that which some power thirsty partners like the Communists prod you to do.These Communists speak all against US, send their children to US to learn & earn, wear Arrow shirts, go to Switzerland for medical treatment- not to China or Russia-and speak about India, Freedom of Speech, Secularism and all other isms as if all the wisdom is with them. They are a set of frustrated, educated and uneducated fools, all bunched together.
