A while ago, I had a multi-topic post covering some things I hoped to expand on. One of them was this

Blowing things and people up is seen as a demonstration of clarity and resolve, unless someone is doing it to us, in which case it’s correctly recognised as cowardly and evil. The most striking recent example (on “our” side) was the instant and near-universal approval of Trump’s bombing of an airfield in Syria, which had no effect at all on events there.

We’ve now had another round of bombing from Trump, and yet more instant applause. As I reread the para above, and looked at evidence on the general ineffectiveness of airstrikes, it struck me that there is a big asymmetry. The satisfaction we get when our side blows something or someone up is trivial in comparison to the hatred generated when we are on the receiving end. In most cases, the people and resources mobilised against the bomber far outweigh the physical destruction the bomber can inflict. Here’s a study (paywalled, but the abstract is clear) making that point about Vietnam; it seems to be entirely general.

I’ve talked here about large-scale aerial bombing, but all of these points apply with equal force to bombing campaigns undertaken on the ground by non-state actors, going back to the “propaganda of the deed” in the 19th century. Experience has shown that deeds like bombings and assassinations make great propaganda, but not for the side that carries them out.
