It's clear that Israel has violated international humanitarian law by indiscriminately killing thousands civilians in Gaza, so rights groups are justified in asking western countries to stop supporting war crimes. The Netherlands has outrageously been complicit in this brutal offensive that goes far beyond targeting Hamas fighters, even failing to call for a ceasefire despite several of its European partners doing so.
While the entire situation in Gaza is an utter tragedy, it is not up to Dutch judges and lawmakers to determine whether or not Israel has violated international laws as it defends itself from Hamas terrorists. Outside of sensationalist reporting, there is no evidence of Israeli war crimes in Gaza, and the Netherlands is doing nothing wrong by sending military equipment under the specifications of pre-arranged deals.
