Failed Nations are a bigger threat to the United States than Stable Nations

I affirm. Good luck! Definitions: Failed Nations: Third World Countries or any country that is unstable. threat: the possibility of completing ruining. Stable Nations: Nations that are financially stable. U.S: United States interests. Clarifications: 1) Failed nations doesn't have fine line. A corrupt government or any form of instability in any government branches shall be taken into consideration as failed nations. Contentions: 1) Failed nations are a greater threat to the U.S' spread of democracy. The U.S wishes to spread democracy, failed nations destroy this because their governments are unstable thus they will rely on dictatorship or communism; take Germany for example, after WW1 their economy & government failed and turned to Hitler and obviously that was a threat. 2) Failed nations are a bigger threat to the U.S' security. For example 9/11 attack supposedly headed by Al Queda, headquartered in Afghanistan, a politically and religiously unstable country, killed many. Therefore failed nations are a bigger threat the the U.S' security. 3) Failed nations brings immigrants, both legal and illegally. I am not advocating on the restricting immigration issue. a)Citizens of a failed nation will immigrate into a better society, namely the U.S. As for the U.S government it must provide for low income families. This drains the U.S government of it's financial resources. b) With a large "import" of immigrants our poverty levels begin to rise therefore crime rates will also increase. This renders our nation unsafe. Because crime rates rise, citizens turn to black markets and gangs, government power is threatened. Not only that but tourism will decline thus the government will lose a large income for public services. Therefore failed nations are a bigger threat the the U.S, financially and in strength terms. In conclusion failed nations are a bigger threat to the U.S' interests, government, financial, and citizens. Rebuttals: 1) No impacts on how it affects the U.S. This argument is pointless. 1a) No link or how it threatens the U.S. Simply talks about how China's industry is a environmental haphazard. 1b) Russia is considered as a failed nation because of its unstable government, a corrupt economy, and houses illegal activities that proves Russia has failed. 2) Overall the U.S benefits from stable nations through stocks,taxing imports,sales tax etc. Here's one situation for stocks: Say China has a stable economy thus U.S stock-buyers buy China's company stocks, the U.S government is able to tax stock buyers' income through stocks thus we are not losing money. 2a) Although we do import quite a bit, don't forget that we also are taxing such imports. This ought to generate quite a sum. Although we do import more we are also acting as a retailer and selling them off at a higher price, thus we will reach a profit. 2b) "If China suddenly decides that its appetite for Treasuries is sated, or worse, decides to start dumping a significant portion of its holdings, a big sale of Treasuries could cause longer-term interest rates to shoot up since bond prices" So what you're saying here is that China owns a "stock" of the U.S government? That's absurd! We all know that the news can be unreliable and that's why Dan Rather, one of the Big 3, stepped down after giving a faulty news report. Thank you for reading. I look forward to Con's arguments.
