this is an interesting thought i had could we have considerd the cold war to be world war 3, it was a conflict between countires that did affect the whole world.
countries were taking sides with russia or america, and it was nuclear arms stand off between the countries. several countries became paranoid of others, and the countries sopy agencies started shoadow wars, so to be technicla world war 3 may have already happened

any thoughts

yes, but this is a looong war. That was just the start, the economics are another phase. So..we could call this WW4??

Some say the next one is WW4 because of the cold war
but the majority is that WW3 didnt happen yet

I think the whole thing with Libya that has ticked off a lot of nations is the starting point.

I don't think that cold war was WW3 because the cold war was just a
race between nations to show their superiority and make a great name
in the world politics.

I wouldn't consider the Cold War WWIII, even though it did affect "world politics".But it was not a "shooting war".One could argue that the 'War On Terrorism" is WWIII......
Hard to say...

it all started with the uprising in egypt. in my opinion

The Cold War is a precursor to the next World War.
Just like the War on Terror, and just like what you see going on with the uprisings and revolutions in the Middle East and North Africa.

The foundations for the next World War are being laid, and have been being laid since the end of WW2.
