IAs we delve deeper into the regional conflicts described in the hypothetical World War 3 scenario we find that each region has its unique dynamics and implications for the broader conflict. Let's analyze these conflicts:

Europe:

• The scenario begins with Russia's aggression in Eastern Europe after the U.S. abandons Ukraine. This leads to instability and delayed responses from Western Europe.
• The use of nuclear weapons results in significant devastation, particularly in Russian cities and military installations.
• The conflict in Europe could have long-lasting political and economic consequences for the continent.

Middle East:

• The Middle East experiences unrest and a race for nuclear weapons between Saudi Arabia and Iran.
• Israel becomes embroiled in conflicts with Iran, Lebanon, Syria, and Pakistan, leading to complex alliances and rivalries.
• The collapse of Pakistan and the use of nuclear weapons by non-state actors raise grave concerns for regional stability.

Asia:

• China's attempt to annex Taiwan is a significant regional flashpoint. The U.S. may or may not intervene.
• The successful damage to U.S. carrier strike groups and limited nuclear exchange between major powers suggest a highly volatile Asian theater.
• Japan's pursuit of nuclear capabilities adds to regional tensions.

Africa:

• The scenario predicts widespread instability, civil wars, insurgency, and terrorism across Africa due to the global war.
• The continent faces severe humanitarian and security challenges, with potential spillover effects on neighboring regions.

South America & Caribbean:

• Venezuela's aggression towards Guyana is a regional conflict with broader implications.
• The collapse of states and the rise of cartels due to global instability have significant consequences for the region.

North America:
