My point of view is that any project that makes reference to a nationality, culture or religion, no matter how good the intention, will attract someones criticism. Even if your project will save millions of lives, if it is attached to nationalistic ideas, it will become a target and attract negative actions from those whose cultural or religious point of view are different. As the saying goes, you can't please everyone.
Now, if you do it in the name of the human race, without any reference to any country, region, culture, religion, ideology, etc... then we may have a chance for acceptance by all.
Of course, language is a difficult obstacle to overcome. Cultural bias, which is propagated through language, is equally difficult to break through. The only universally human action I know of is compassion. Not love, not hate, not fear, although those are considered universal feelings, their causes or triggering acts are dependent upon the culture. Only compassion, the act of selflessly helping a person in need, is free from any selfish stains.
Of course, my statement is based upon buddhist thoughts, and is inspired from the effect of karma and the law of cause and effect. Any action that is assosciated to an intention or desire will generate karma, which will inevitably return a reaction. Selfless compassion is not dependent on personal desire nor intention. Selfless compassion flows from the situation at hand. It is performed according to one's own capacity and abilities. But even if one has nothing material to offer in any situation, one can always offer selfless compassion. Being present and listening to someone's grief without judging nor criticising is an example of what I'm talking about.
So, let people offer solutions to this planet's problems, each in their own way, according to their best abilities and resources, but please let go of any references to countries, nationalities, culture or religions. Those are the worst justifications to do anything because they are not universal. If someone has something to offer, let them do it selflessly, as a gift to life. And if someone start to say something like "oh, this is a german idea!" or "this will profit the Phillippino people", just show these people the error of their views by letting them see the results of our actions.
