well, your definition of Patritism is debatable. I don;t think that US is trust worthy, see what has hapenned to IRAQ, we cannot sigh any accord with US where we become too dependant upon them one day that for even eating food , we may have to get a permission.
Moerover, India is anyway a big threat to US as far as this part of the Globe is concerned. US can just not digest a compititor growing....
Since, US has not been able to convince India in signing NTPT, it has changed its policy towards India and has brought this deal to tempt India indirectly.
Such big decisions are not taken thinking that the man doing it is a Patriot, lets not be so emotional as far as decisions regarding the whole country is concerned.
