I've begun to worry. It's possibly that war may happen. Many people have said that they want to kill the attackers and the people of their countries. Many have already died; if more die, how will that help? And it's not even known (for sure) who attacked.
We've seen in the past that if someone kills one person, the other kills several people in revenge; no-one will stop, and things will keep getting worse.
And it's not just a matter of the United States. The US asked NATO for their help and support. Soldiers from many countries may fight, and war may come to many countries.
I read today that two terrorists lived in Hamburg. One of them lived in Harburg, where he studied, for eight years -- south of the Elbe, and only 2.5 km (1.5 miles) from my house.
 I used "seven" in the Cadhinor because I thought I'd pick a "magic" number. According to Shm Revouse's grammar of Cadhinor, seven is a sacred number; for example, there are seven Thinking Kinds. So I thought seven might be appropriate in such a context; it's meant as an indefinite "several".
 literally, "person in charge of terror", from encais + -rion.
 I used the Verdurian preposition "po" here since I couldn't find a Cadhinor equivalent.
