I think the missile the Elbonian is carrying may be a remanent of that old war they had with that developed country, the one were said country tried with no effect but raise his national income (when your exporting production is mud, there is not mcuh to destroy, and any missile that fail to explode is a profit)
Am too lazy to look for those strips, they are old and that' s all I know.
"Dilbert" has mostly been a non-politics zone where all of us, regardless of nationality and religion, can share our frustration from our crazy employers.
For politics, there are plenty of appropriate web sites. Taking Israel-Palestine into Dilbert makes as much sense as forcefully plugging it into any other subject, such as sports, music, cooking etc.
For that matter I could be a palestinian or an israeli but I would still consider this off-topic.
