Any trade barrier almost always ends up hitting our own people. we have protective barriers to protect critical fields like agriculture.
I think there is one place we can hit. Its Aircrafts. Boeing has a massive order from Tatas, they can delay those planes and look for second hand airbuses in interim. That will be an immediate and visible retaliation.
Other place is aircraft engine tech. i think we are already moving to french for partnership in making engine.
So yeah...
We don't have much trade leverage with the US & neither do they with us. If Trump tinkers around with IT support systems he risks jeopardizing all those Silicon Valley set ups which aided his campaign . We won't be touching this sector any time soon too .
Pharma is self explanatory which leaves defence. If Trump touches that aspect of our relationship we'd be in deep trouble no doubt given our upcoming appointment with China but then Trump would've irrevocably damaged Indo US ties.
Up until now it's still a trade dispute & a limited one at that . The idea from our perspective is to keep it at that at worst , at best to resolve it without long lasting damage to our interests .
What we need is patience , a virtue at the best of times , more so now in the age of 24x 7 news media & SM with a story breaking out every 15 minutes .
The action on the validity of Trump's tariffs has moved to the SCOTUS . Even otherwise the toll it's taking on US agriculture , big & especially small business has already started making waves in the media. It's only poised to get worse .
See Trump's & his courtiers daily rants in this light. It's to bully hold outs like India. Finally you've to remember one of the reasons the US commands enormous respect around the world is coz of the security guarantees it provides its allies.
The EU said as much when agreeing to the unilateral business deal in Trump's favour as justification in the hope that the US won't throw Zelensky under the bus & continue backing Ukraine especially Europe's support to him.
Ditto for Japan & RoK . Now comes news the new defence policy is going to be a 180° turn from traditional US position. They're going to focus more on homeland security than pursue international obligations & / or interests.
That screws up Quad , Japan , Taiwan , RoK etc much more than it does Europe against the Russians for while the latter doesn't have designs as on date on Europe even though Europe is crying wolf , China has territorial claims on the all aforementioned parties which in turn means all those unilateral one sided deals they've struck with Trump is Trump suckering them while throwing them under the bus.
This latest defence policy is going to cause a storm across party lines in the US . It all but encourages Chinese aggression giving them a Carte Blanche to do as they please.
If there's a deep state in the US this is crossing several red lines at once for it diminishes the pre eminent position of the US , something the former has spent decades since the end of WW-2 building up only for a maverick to come dismantle it in the very first year of his presidency .
This will have severe repercussions on the US if Trump doesn't course correct which I don't see him doing . This in turn will prompt those elements to undermine Trump & you've no clue how far they're prepared to go . Check out how Kennedy & Nixon were taken care of for perspective.
