My dear learned friend , please study the figures of Indian Exports and Imports to understand the tilt. Indian Imports are much higher than her Exports! and that itself should justify a strong rupee. As far as USA trying to weaken the dollar is concerned , it is as true as the WMD's in Iraq. USA is in deep economic troubles due to the Wars it is supporting in Iraq & Afghanisthan and also the large scale outsourcing happening(which definitely is helping countries like India) at the cost of USA citizens. Even after doing their best to create Jobs in USA , the unemployment figures are alarming !So , presently USA & it's dollar are on a very weak wicket.
