I am not a supporter of the current Indian Establishment but invading USA is beyond the capability of India or most nations. USA is called Fortress America for a reason.
Besides, for the current, USA can have a defensive military which naturally will be a much scaled down version but enough. Getting rid of its aircraft carriers and bomber planes will be a good start towards signalling peace.
US is #1 for so long because we don't become complacent. What you are asking for is complacency and to be frank world peace is a pipe dream.
