When you provide a general purpose donation to a charity, you're giving them a gift. You're entrusting them to do with it what they think is best. If you don't trust them to do the right thing, don't give them the money in the first place, or donate to a specific campaign if they offer such opportunities.

Unless they turn out to be deceitful, duplicitous, or otherwise exceptionally wasteful, second guessing and/or judging their decision making process from the outside isn't likely to be a particularly fruitful endeavour for any of the parties involved.

If you want to explicitly target a very narrow case, you need to donate explicitly to that very narrow case. There are NPOs and charities that provide this kind of explicit service[0], for narrow targeted funding where you control exactly where your money goes. If you donate to an organisation with a broader mission, you shouldn't have any specific expectations of where that money is spent.
