I've always wondered if on September 11, 2001, terrorists had attacked the Eiffel Tower in France or the parliament building in Germany, how would those countries feel?

The very same countries who blasted our near obsession with anything Al Qaeda (search), as one French newspaper put it, would they obsess too?

What got me thinking is a New York Times piece on Friday on the suddenly shaken Saudis dealing with homegrown terror of their own after that Riyadh attack this week. At least seven of the victims were natives and, as The Times reports, the 15 attackers probably were too.

How could this happen, they ask? It didn't seem as pressing to them when it didn't concern them.

It didn't seem to matter that 15 of the 19 Sept. 11 hijackers were from Saudi Arabia, as long as they didn't do any harm to Saudi Arabia.

And it didn't seem to matter that Al Qaeda showed no respect to countries hit, as long, I guess, as it wasn't the Saudi country hit.

We all know, of course, terrorists draw no distinctions, no boundaries and no exceptions. Targets are targets, whether in U.S. skyscrapers, or Indonesian shops, or French tankers, or a Riyadh compound.

Somehow some believe that if you keep your head down, you won't be blown up. That if you don't incite the bully, you won't be bothered by the bully.

It's sad that it takes losing your own people to see the vulnerability of all people.

We're all in this together, my friends, whether we like it, or not.
