In a landmark ruling in mid-February, the Hague Court of Appeal ordered the Dutch government to stop exporting parts for the Lockheed Martin F-35 Lightning II to Israel, citing the risk of serious violations of international humanitarian law if the F-35 were used for airstrikes in Gaza. Although it seems unlikely that the court order will have any significant impact on Israeli air operations, it raises a number of legal and political challenges to the global F-35 program, the U.S. Department of Defense’s most ambitious and most expensive weapons program to date.
