Even if the article's author had any clue what they were writing about, I don't see how this could ever work.
First, whether the U.S. trusts foreign security screening is normally irrelevant since all non-preclearance passengers have access to all the sharp and liquid things in their checked luggage while clearing customs.
Second, India doesn't even trust its own security screening. I can fly GJT-DEN-ORD-AMS-HEL-RIX without ever reclearing security, but HYD-DEL-IXC requires reclearing security in Delhi. Also, TSA allows scary stuff like small pliers and cigarette lighters on flights, so I don't see the Indian authorities signing off on that. Don't tell them about how security at HEL let me through with a Swiss Army knife and a bottle of booze.
