In his drasha on Shabbos, Rabbi Welcher pointed out that according to the Rambam, Darchei Shalom obligates us to assist, where help is needed. Therefore we should donate funds to help the Asian Relief Effort. In a follow up question after Shul, he suggested we give through Jewish organizations to increase the Kiddush Hashem. Here is the link for the OU's Asian Relief Fund, where you can donate online via credit card. You can also mail a check to:
