Journalist Yaari Cohen posted a video of an Israeli Merkava Tank rolling over an “I Love Gaza” art piece at the Rafah border crossing.
The American Law of Armed Conflict and International Humanitarian law specify that “military necessity” permits measures which are actually necessary to accomplish a legitimate military purpose.

Destroy only what you need to accomplish the mission.
