We are not just to "remember Amalek," like we "remember" the Shabbat, lihavidil, to differentiate, we're supposed to always remember what Amalek did to us when we had just left Egypt and felt confused, full of doubt, lacking confidence etc. That's when Amalek attacked.
Today at our Women's Shabbat Class, when Rabbi Dov Berkovits told us to think of the situations when Amalek had attacked us, I suddenly thought of the nascent Jewish State in 1948, when trying to absorb the survivors of the Nazi death camps...
Did any country actually help and support the struggling Jewish State? NO!
When we were our physically weakest, the Arabs attacked and the world continued their silence. The same silence they exhibited before and during World War Two when Nazis were first discriminating against and then murdering Jews.
There were even countries, such as Great Britain which even helped the Arabs.
And standing by is no better than.
We must remember that push comes to shove, we, the State of Israel has no real ally. There's no country that would risk anything for us.
Yes, it's a Torah requirement, commandment, Mitzvah, to REMEMBER!
