• One of the main national security concerns is the potential risk of technological espionage by the US as they could gain access to sensitive data and information about India's national security. Considering the geopolitical rivalry between the two countries, this could pose a significant security threat.
• Another concern is that the drones could be used for targeted killings, which would violate India's sovereignty and could raise ethical and legal questions.
• The US may also impose restrictions on the use of the drones or limit India's access to its technology, which could adversely impact India's defense capabilities and overall national security.
• The procurement of drones from the US could also increase the risk of cyber attacks or hacking, which could undermine India's national security.

It is essential for India to carefully consider these potential risks and ensure that appropriate measures are in place to prevent any security breaches or technological espionage. The government must also ensure that the deal does not compromise India's sovereignty or violate international laws and norms.
