No, because they are not taking part of the hostilities, however aiding Hamas or any other terrorist organization by the way is a crime, baring the same responsibility for the crime committed as well.And members of Hamas that erect street lights along Gazan roads, should they be killed to?You wrong again Billo..Really... killing Hamas members is fully justified, unless they surrender and extradite themselves they are always posing a threat to innocents, and every day is a good day to kill them.
Here is the example, the driver [Hamas member or not] that assisted the terrorist who fired the rocket that killed Daniel (the 4 years old boy) baring the same responsibility for committing a murder, collaborating and taking part of forbidden terrorist organization, and whatever else, but for itself its a disgraceful war crime.
