Don't be put off by all the stories of aid being diverted to weapons. Don't use it as just another excuse not to give.
We Buddhists like giving. It's one of the four noble truths that people are made unhappy by going around wanting things. Conversely, not wanting things will make you happier and you can be even happier still by giving things away.
Don't worry if you're a rather poor person whose wants largely consist of your next square meal and a working bar on the electric fire, because you don't have to give money. You can give time, expertise and energy, and many charity premises already have their own electric fires. You can even just give a Mother's Day card (although this will involve wanting a Mother's Day card and then wanting the money to buy it with, both of which could make you very unhappy, so give it away quickly).
