Lel! So juvenile, 'with stroke of a pen'.. Seriously dude. How exactly are you going to destroy India? I don't have any idea what exactly you are talking about. Possibly you don't know either. To give a summary, you started off by saying Americans can replace Indians in six months for coding. Then talked about Canadian docs going on strike, replaced by Turkish docs.
Should I say Indian export to the US are not just 'codes'?
Or if you're are talking about H1B's then you must know the remittance to India from the US means zilch. Yet again, are you talking about US investments?
It's best to stop talking to you since you are not actually talking to the point. As for India imposing Tariffs on US products, didn't the US put tariffs on Indian steel exports? Tit for tat
