The sanctions imposed on Russia as an aftermath of invasion on Ukraine and India’s stand on the issue has put USA in a dilemma.
Ostensibly this cannot be hidden from US law makers and its security experts that the sanctions imposed on Russia and its weapon manufacturing companies will have an adverse impact on India’s defense capabilities as almost 50% of India's def hardware is imported from Russia and there are numerous other Joint ventures related to defense equipment which will be severely impacted.
The US decision makers would have also appreciated that sanctions on Russia will seriously imperil India’s operational efficiency which faces military threat from a much stronger enemy China with whom India had a bloody skirmish just a year ago at Galwan.
In addition to above they must also be conscious of the fact that over last two decades India has emerged as an undeclared Frontline state of US against its long term enemy China and is also an important member of Quad which is an important Anti China alliance.
The fact that USA did not impose any sanctions under CAATSA (COUNTERING AMERICA’S ADVERSARIES THROUGH SANCTIONS ACT) on India after it deployed S400 Air Def system imported from Russia whereas it did so against China and also against Turkey is a testimony that US treats India differently and it is quite possible that it may turn a Nelson’s eye towards India again on fulfilling its crucial military needs from Russia.
Biden , the US President must appreciate that a stronger India will be to its advanatge and if India needs US assistance, US can not undermine the fact that it also needs India on its side to deal with China in Indo - Pacific Region.
But I think the above may only be possible if the war ends at the earliest and it does not lead to unprecedented levels of destruction and loss of civilian lives.
