I’m not arab, but as he said, you can worry about more than one thing. But I think the biggest difference with your tuberculosis example is: One is a problem due to lack of action, the other a problem due to direct action. You have to be competent to do something about one, while the other, just by not doing anything (by not giving them loads of money and weapons) they would already solve the problem.
So one problem requires effort to be solved, the other, they are putting effort to create the problem and it would be as easy as just not doing it. In theory pressuring them in just not doing something should be easier than doing other work.
Put in a different view, what would be your worse behaviour?
-A person you know died of turberculosis and you didn’t take them to the hospital
-A person you know died because you shoot them, or you gave someone a gun and money and told them they could shoot them?
Which action would get more people against you?
Sorry, your scenario is too stretched for me to comment on it.
I can only comment regarding their patent system and I 100% agree that the north american patent system is a cancer on the entire world. A massive problem that needs addressing. But as mentioned before, you can worry, and work on more than one problem without invalidating them. But that problem involves much more variables and powerful companies/ people/ countries to be resolved. I won’t comment if that is the solution for the problem you present since I think it’s more complicated than that. But, again, I think destroying the north american patent system would benefit the whole mankind. I just have no idea how that can be solved without the whole world going against them.
The rest, I guess I can only say that you can’t judge which battles people decide to fight, if you agree they are fighting something bad. You fight to demolish their patent system and others fight to end their imperialism. Both fights are valid and everyone except the abusers would benefit from them.
