Saddam and Shul
I'd be interested to hear what people did in shul Sunday morning in response to the capture of Saddam. I'll relate what I would have done (and what we did).
How do we define, halakhicly, this occasion?
Let's compare it to (a) victory in war against an enemy who wishes to destroy us, (b) the death of an enemy of humanity, (c) death of an enemy of Jews, (d) capture of B or (e) capture of C.
This is the capture of an enemy of Jews (E) and, one can say, the end of a war (A). Even though there's still guerilla warfare in Iraq (e.g. the suicide-slay of 17 people on the very day of Saddam's capture), there's no pretext for the war anymore.
Saddam was a specific enemy of the Jews. Because of the Bush mumbo-jumbo, people forget that Saddam declared unilateral war against Israel in 1991. He was also an enemy of humanity (mass murderer, tyrant, rapist, you name it) but the fact that he particularly aimed his destruction against Jews creates a halakhic reality.
Even if we catch Osama, we won't treat that occasion in the same way. Osama is an enemy of humanity. If we had run in and captured Stalin, we could say he was a target of Jews (although he did vote for the formation of Israel, go figure).
Also, the fact that we captured the enemy alive is a big joy. Killing an enemy, of having the enemy die of other means, is not the same level of joy about God's help. When Arafat dies, bimheira b'yameinu, even if its at the hands of the good guys, doesn't make it a day of true simcha. If we capture him (and put him on trial) then maybe so.
My conclusion was that since Saddam was a specific, unrepentant, enemy of the Jews as well as an enemy of humanity, who was captured by the good guys to be brought to justice, I consider it a day to (a) say Hallel (without a bracha, because I lack that level of authority), and (b) not say tachanun.
No tachanun for the morning, not the day, as in a bris. The joy was of the moment, when we heard the news (even though it had taken place earlier). Tachanun would be back at mincha.
Hallel without a bracha is known as "Tehillim 113-118." A simple way to recognize and thank God.
What we did in shul was: (a) no tachanun, (b) we said aloud, in unison, Mizmor l'Todah and Ezrat Avoteinu (the bracha between Shema and Shemona Esrei), (c) before Shir shel Yom, Rabbi Lookstein told us that this is a day of joy mixed with the sadness that we arrived at the day only after many lives were lost - we were enjoined to give more tzedaka and do teshuva in recognition and thanks, we then added Pslams 121, 124, 125, 130, and 134.
