NOpe we have always had conflict.  Man kind is always killing someone or going nutz somewhere.

There is climate change and the country most impacted by it is China. China has 80% of the world's factories and has extremely high rates of pollution. There is no such thing as human rights in China, they are not even allowed to vote. The water in most parts of China is contaminated. So long as climate change is not directly impacting your life it is all fine and dandy. 

China produces the world's goods, government oppresses its people and the goods get sold all around the world. Big businesses and Chinese government: win, win. 

China has a 200 million Strong Red Army. That is a lot of man power. China has been building its military for 20 years. Navy, Army and Military are growing day by day. China growing stronger as it becomes more industrialised and consumes more and more raw materials from the mineral export nations. 

China becomes a super power it will want to expand its nation by consent or conquest. The US will have to decide on whether to allow China to expand its territory or confront the Red Chinese juggernaut. 

Well honestly as a pro-globalisation person I think China is showing the rest of the world exactly what to do. Do I think American's should stop buying foreign made products to promote American ones instead? No. Canada for example exports almost everything we make all of our natural resources etc...etc... then we import all the products we need. It works well with global trade.

But if American's only bought American products, Canadian's only bought Canadian products , China only bought Chinese products. Well the world economies would collapse. Countries where manufacturing is their economy like China would go belly up and countries reliant on natural resources like Canada would have nobody to cheaply manufacture products out of them. Then the US which imports and exports almost as much. Would be paralized without the natural resources from Canada and cheap food from Mexico, Canada and South America. Fact is we should be buying multinational products to support the global economy and help the countries we are buying from.

War would be the best thing for the US economy right now. Getting all the factories back up and running for war production would eliminate unemployment and get the economy back on track like it did after the depression. 

Also I highly doubt China will come to North Korea's aid if there's a Korean War II. I highly doubt China wants a war with the United States. They know they'd get crushed. I know China has a ton of people but most of them are untrained and uneducated so they really wouldn't be much of a military I don't think aside from sheer numbers of people.

I agree with you somewhat but I don't think printing more money works. Isn't that what Germany tried to do in WWII and it basically made their money worth nothing more than the paper it was on?

War fought by other countries like WW2 - yes. War that involve US Army heavily in risky land operations (not to mention politicans will have problems to justify such war) - bold "no", you don't really need to kill that many Americans to heat up political conflicts inside country to the degree that it will have serious consequences and backlash, e.g. Vietnam War.

USA did a lot more than you think in WWII (in Europe), plus they took out Japan by themselves. I know Russia (Soviet Union) did the most in Europe but USA did their part as well.

Also I don't really know why people say the US not helping in WWII makes them less of a country or whatever. How was it in any way their war to fight? They said right from the beginning they wouldn't get involved in a war in Europe. It wasn't until Japan attacked them that it became their war to fight.

And USA could easily win a war against China, especially if they were allowed to use the full extent of their resources. By that I mean things like carpet bombings of highly populated cities in China like Shanghai and Beijing. 

1) That's a bit off-topic, but consider this: a) US involvement into WW2 was highly justified (patriotic rhetorics like "those japanese bastards perfidious attacked Pearl Harbor, let's strike them back, yay!", though at the same time it was a big f*ck up of US intelligence, the big reason why attack was "sudden"), to the contrary a direct invasion to China, if that what you're proposing, is hard to justify at this point, unless a brilliant provocation opertion is executed; b) if US would have involved into WW2 in Europe from day one they'd have steamrolled by Wehrmacht just like French, Brits or as a matter of fact Soviets in first year of war, which means a complete and shameful withdrawal of US forces from Europe (I'm not a big expert on war in Pacific Ocean, but judging by US military operations in 1944-1945 in Europe, US army seriously lack experience in big on-land operations and pale in comparison to the Soviets in the same time frame from other side of the front). BTW speaking about war against Japan, read more on "Manchurian Strategic Offensive Operation".

2) Really, I don't mind pave your way to self-destruction =)

China is a threat only in their support for the evil regimes like NK and Burma etc.

The world is higly interdependent meaning there are limitations to what a country can do or dont do.

America will still have the most powerful military for a long time even after China becomes a larger economy (if of course, we don't know the future). So there will be balance between the US and the rest of the west, a resurgent Russia, China and India.
