Nah, the thing is NATO loves doing it

The US Navy used sea-launched Tomahawk missiles with Kit-2 warheads, involving reels of carbon fibers, in Iraq as part of Operation Desert Storm during the Gulf War in 1991, where it disabled about 85% of the electricity supply. The US Air Force used the CBU-94, dropped by F-117 Nighthawks, during the NATO bombing of Yugoslavia on 2 May 1999, where it disabled more than 70% national grid electricity supply. The supply was restored in less than 24 hours though was later disrupted by a further attack on 7 May 1999. It was again used following the 2003 invasion of Iraq.

So all western controlled human rights agencies just say it’s “questionable” or it’s cool because power supply is of dual use, like Human Rights Watch:

Coalition forces did, however, identify certain targets as “dual use,” including electricity and media installations. Human Rights Watch’s investigations found that air strikes on civilian power distribution facilities in al-Nasiriyya caused serious civilian suffering and that the legality of the attacks on media installations was questionable.

what the use of an emp(in effect) equivalent that doesn’t kill people(directly)? or that it would target civilian infrastructure (like conventional weapons also do)?
