Trump needs to be careful. Destroying civilian power plants can be unlawful. Front the net… Attacks become unlawful — and potentially war crimes — in several common scenarios involving power infrastructure: 1. The power plant/grid is a civilian object — If it does not make an effective contribution to military action (or if there is doubt, it must be presumed civilian), attacking it violates the prohibition on directing attacks against civilian objects (Additional Protocol I, Article 52; customary Rule 7). This is a war crime under the Rome Statute (Article 8(2)(b)(ii)). 2. Disproportionate harm — Even if it is a military objective, the expected incidental loss of civilian life, injury, or damage to civilian objects (hospitals, water supply, heating in winter, etc.) must not be excessive relative to the concrete and direct military advantage (Additional Protocol I, Article 51(5)(b); customary Rule 14). Widespread blackouts causing severe civilian suffering (e.g., lack of heat, water pumping, medical care) often fail this test. This can be a war crime (Rome Statute Article 8(2)(b)(iv)). 3. Primary purpose is to terrorize civilians — Attacks whose main aim is spreading terror among the civilian population are prohibited (Additional Protocol I, Article 51(2); customary Rule 2). 4. Starvation or denial of essential services — If the intent is to destroy/deny objects indispensable to civilian survival (not just military denial), it may violate rules against starvation as a method of warfare (Additional Protocol I, Article 54; customary Rule 54). Power infrastructure isn’t explicitly listed like food/water, but widespread, long-term deprivation of electricity (affecting water, heating, hospitals) can cross into this territory, especially if systematic. 5. Special case: nuclear power plants — These (and dams/dykes) have extra protection as “works containing dangerous forces” (Additional Protocol I, Article 56; customary Rule 42). They generally cannot be attacked even if military objectives, if it risks releasing dangerous forces and severe civilian losses. Violating this is a grave breach/war crime in many cases.
