Again, the fact that the US makes mistakes, and has made mistakes throughout its history, doesn't mean they're just as bad as China, that is currently ethnically cleansing minorities throughout its territory, or Russia, that literally invaded its neighbor and has been raping its neighbor's women and kidnapping its neighbor's children over the past three years.
Afghanistan is absolutely different. The country allowed Al Qaida to operate with impunity in their territory, and then protected them even after 9/11. And while I was never a fan of the war in Iraq (protested against it even), Saddam Hussein was an evil and dangerous man who used chemical weapons on his own people. Now there are lots of evil and dangerous leaders around the world, and again, I was against the war, but claiming that the war to remove him was "no different" from an autocrat invading another country simply because he wants its territory is absurd.
We know better now! Is the correct answer, "well we now know it's killing the planet, but we have to be fair, so go ahead and continue killing the planet?" Of course not. That's like arguing that "my grandparents could buy cigarettes as teenagers because no one know smoking was bad for you, therefore the government shouldn't be allowed to ban the sale of cigarettes to minors because that wouldn't be fair". Ludicrous argument.
The US government were covering up friendly fire kills on its own soldiers in the whole Snowden episode. Those families would never have found out exactly what happened if it wasn't leaked. US passed an act in 1830 to be able to forcibly remove Native Americans from their lands. You can bet your life soldiers raped and abused some along the way. By your argument what China is doing now will just be a mistake in its history when looking back on it in years to come.
This high and mighty mission in Afghanistan, what has happened since? They high tailed it out of there and abandoned the country to allow it to return to terrorist rule, wasting thousands of lives both civilian and the soldiers who fought in it. What must those families of those killed US and UK troops be feeling, that their sons and daughters died or got maimed for nothing. As for Iraq that was a joke, yes Saddam deserved to die but in doing so they destabilised the region and it's still not recovered since.
What did Trump just say on the news yesterday? Incoming President, he would not rule out taking the Panama Canal and Greenland by force. I believe that's one country wanting to invade another country simply because they want their territory. Also the Gulf of America statements and Canada becoming the 51st state.....
The correct answer is that climate change and fossil fuels would not be an issue if it wasn't for global overpopulation. That's what really killing the planet. Too many people taking up finite resources at an increasing rate.
If the global powers truly cared about climate change then why is nearly every country in the world outsourcing production to Asian countries where there is cheap labour exploitation and the countries burn a lot of fossil fuels. They are indirectly using fossil fuels themselves but by adding the cost of it to another countries total output. If Apple cared so much they would produce everything in the US using renewable energy.
