Big Question: From Vladimir Putin's expansionist aims to the advances of Islamic State, the news is full of threats to global stability - but what do specialists in war studies think we should fear most?

A group of Chinese warships led by the country's sole aircraft carrier entered the top half of the South China Sea on Monday after passing south of Taiwan, the self-ruled island's Defense Ministry said of what China has termed a routine exercise.

The move comes amid renewed tension over Taiwan, which Beijing claims as its own, ineligible for state-to-state relations, following U.S. President-elect Donald Trump's telephone call with the island's president that upset Beijing.
