It often results from explosions, impacts, burning vehicles and buildings, and many other acts of war. Surprisingly, many fires have occured in wars that did not require white phosphorus to set them off.

The "white phosphorus" is crap.

Deliberate killing of civilians with smaller weapons does not excuse the practice. If Hezbollah had bigger weapons, there wouldn't be an Israeli left alive. Hezbollah would use the nukes Israel does not. Hezbollah would wipe out every Israeli down to the last child and celebrate about it for years if they could. They have said so. Did you read either of those links?

Remember, every single rocket launched by Hezbollah is aimed specifically at civilians. Try to find one, just one, launched at anything resembling a military target.

Where do you go in this country to learn to side with any monster over your own civilization?
