Your facts may be correct, but I see nothing here to explain exactly why Clinton had to commence the bombing on the very same day as the scheduled impeachment vote.
The bombing commenced on December 17, the SAME DAY that the House of Representatives was scheduled to vote on the Articles of Impeachment.
The clear objective was to delay the vote until the end of the term, only a couple of weeks away, so that the vote would be taken up in the new term where there would be more 5 more Democrats seated (and thus a greater likelihood that Clinton would win the vote and avoid impeachment).
With great self-righteousness, the Democratic House leadership publicly called for a postponement of the impeachment proceedings, arguing that America must unite behind the President while our troops were in harms way, and that the imeachment vote should not proceed as long as the military action continued.
The House agreed to postpone the vote, but only for one day, and it was held on December 18. Virtually as soon as it became evident that the Impeachment would proceed anyway, Clinton called off the bombing campaign.
Afterwards, Clinton and Secretary of Defense William Cohen stated publicly that the Baghdad bombing campaign had set back Saddam's WMD program by at least a year.
Incidentally, Congress was not consulted and NEVER voted to allow Clinton to undertake this bombing.
Needs to be repeated often and loudly!
