To begin with, let's consider criteria and that means we need to ask "dangerous to whom?" There are plenty of local actors who are the nearest, greatest threats to the neighbors. So, let's limit ourselves to actors who can cause the greatest disruption through their actions to the most people over the next decade or so.
Here are my top 10:

10. Venezuela





9. Iraq and Saudi Arabia (Tie)





8. The European Union




7. Nigeria and Congo (Tie)

&


6. Israel and Palestine (Tie)

&



5. Iran





4. Russia





3. Pakistan





2. China





1. The United States

Which country do you think is the most dangerous one in the world?

Uhh..

I think Pakistan should be first.

(country)I think USA.They are taking us for the 3rd world war faster than any country in the world.
(region)Middle East from the ocean to the ocean.Every one want a piece of M.E cake.
I just want to imagin the 3rd world war(oh god).

How can the European Union can be most dangerous place in one place?

australia... don't you know we have jaws the shark?
but on a more serious note pakistan is a serios threat to nearly everyone and I'm also very surprised dprk didn't make the top ten...

Pakistan is a serious problem to every single country in the world. I am absolutely astounded at how poorly protected their nuclear arnaments are.

I remember about a month ago when I was watching the news they made a report that terrorists have the ability to steal nukes from Pakistan because they are poorly defended.

Absoultely apalling.

don't believe everything you hear in news the Pakistan military is largely a law unto themselves and the only reason this is so is because they have the nukes and let me tell you they will never let that happen or all their power goes bye bye...

I know, I found out on Sunrise but I was disgusted enough to beleive it.

Anyways, back on topic:

As you said before, I think DPRK should be up there instead of Venezuela [But a bit lower down the list], MAYBE Somalia should be at tenth cause of all those ruddy pirates.
