Are there are any current situations in the world that relate to the novel? what are they, and how do they relate? Does the novel shed anylight on how current situations could be resolved or “fixed”?

Yes, there are current situations in the world that relate to the novel. The situation that I want to talk about is the war in Iraq. This war occurred because there was a terrorist attack in America. Four planes were hijacked by nineteen terrorists. After the planes were hijacked, two planes headed towards the World Trade Centers. Both of those planes intentionally crashed into each of the World Trade Centers. One of the other two left crashed into the pentagon. The remaining, last plane crashed into a field because the passengers on the plane tried to take control of the airplane again. Because of the damage caused by the planes, President Bush declared war on Iraq. America knew it was Iraq who caused the terrorizing because pictures of those nineteen terrorists were sent by Osama bin Ladin (the leader).This situation relates to the book in one way. In the novel, Earth was invaded by buggers. After the invasion, Earth decided to attack back so they invaded the buggers too. Just like that, America was invaded by Iraq. As a result, America decided to also invade Iraq.
I do not think this novel shows a way to resolve the conflict. The reason is that America's reason of staying in Iraq changed. The president of America decided that America needed oil. Now America's main reason of staying in Iraq is because of oil. Iraq is abundant of oil. Still, even though the reason of staying in Iraq didn't change, America cannot use the way the novel used to stop. The reason is because this would cause genocide. In the novel, Ender completely destroyed the buggers. In real life, America wouldn't think of killing all the people in Iraq. That would sort of cause a world war.
