The more I see and study the world, the more convinced I am that the biggest problem of our time is that the globe is divided into countries. Individuals, in general, choose to maintain or remove political leaders according to what they think is best for themselves. For example, no one votes thinking "oh, this guy/girl will be terrible for me and my country but will be amazing for the world, so I will vote for him/her." Individuals support leaders thinking primarily on their own good, not the good of others. Political leaders want to stay in power so they will do/say whatever their electorate thinks is best for them, even if it makes the rest of the world worse off: let the amazon forest burn, start trade or currency wars, close borders to foreigners fleeing wars, etc.
As long as the world is divided into countries and only the population of each country can choose their own leaders these tragedies will continue to happen. There is relatively little foreign states can do to influence governments abroad as sovereign countries are free to choose their own policies. In my view, the only way to stop these tragedies is to get to the root of the problem, i.e. removing all country borders. Otherwise, despite all the protests around the world, less than 25% of war refugees will be allowed to live in developed countries (as it continues to be the situation with the Syrian refugees), Trump will continue its economic war with China (potentially leading to the global recession in the next couple of years), the Amazon forest will continue to burn, among many others.
