This Shabbat and Sunday marks a period where we will read about the wiping out of Amalek 5 times within 24 hours (or at least, no more than 36 hours):
- Parshat Zachor
- Haftara from Shemuel
- Mikra Megilla on Saturday night
- Parshat Amalek Sunday morning
- Mikra Megilla Sunday morning
The destruction of Amalek, besides being a Mitzvat Aseh, is a vital part of the Ge'ula process. It is the act that will make Hashem's Name complete and His Throne complete.
Here are a list of jblogs that have discussed Amalek recently:

Also, the leader of Iran may have more than deeds in common with Amalek:
If you spell his first name as מהמוד, his gematria equals המן (see Hashem1.net for an explanation having to do with the Farsi language).
If you spell his last name as אחמדיננעג'ד, his gematria equals עמלק.
Purim Torah, you say?
