A single cost-cutting decision to an expensive naval project is in itself a mere adjustment. But in a wider context it highlights the missing debate about Britain's 21st-century security needs.

The emphasis on armed-drones is transforming the United States's counterinsurgency strategy. But their capacity for proliferation carries acute and so far unrecognised dangers for Washington and its allies.

A new phase of violence in Iraq and the dynamics of the conflict in Syria provide fertile conditions for the re-emergence of the al-Qaida idea.

The Taliban assault on key sites in central Kabul highlights the strategic predicament of the United States and its Nato allies in Afghanistan. The forewarnings were present a decade ago, in ways that still cast a shadow on the present and future.

The global power-balance is being changed by the rise of the non-western "Brics" states. This makes the pioneering work of a body committed to linking trade and development in the interest of the world's poor more relevant than ever.

The international tensions around Tehran’s nuclear programme have eased as diplomatic talks are agreed. But the intensive planning in Israel for an assault on Iran continues. This makes it vital to understand the scale and probable consequences of a war.

A major environment conference in mid-2012 may help reset the faltering argument for a great effort to address global climate change. The emerging science on "extreme weather events" shows why the challenge is becoming urgent.

The alarming pace of events in Afghanistan is forcing United States and Nato strategists to adjust their strategy and timetable to end the war. But they cannot acknowledge the flaw at the heart of their efforts.

The Syrian regime's violent repression persists, in a context of regional rivalries that fuel the country's conflict. The ensuing impasse also reflects the dominance of state interests over international justice.

The military-political interplay in Afghanistan is taking an alarming new tilt for Washington. The possibility of a more precipitous exit is rising.

Israel will seek United States endorsement for any decision to confront Iran - but its allies there will more likely to be found in the heartland than in the White House.

A military build-up, harsh rhetoric, third-country attacks - and the political calendar - make war against Iran a real possibility. It is the more vital that those attempting to avert it should succeed.

Washington's military withdrawal from Iraq and problems in Afghanistan are forcing a change of strategy. Barack Obama's political fate will determine how far it will go.

A range of military and political developments, from the very rare planned deployment of three huge United States armadas in the Persian Gulf to Israeli fears of Barack Obama’s re-election, is evidence of rising danger around Iran.

A sense of enduring history and more recent experience of bitter conflict inform Iran's nuclear stance. To understand this could be a way to avoid war.

The prognosis of a thirty-year war looked outlandish as Saddam's regime toppled, persuasive as Iraq's insurgency erupted - and now less plausible amid American forces' retreat. But two core issues continue to give it life.

There is powerful evidence for the argument that the al-Qaida movement is in decline. But there are other processes at work - including in United States presidential politics - that could yet create a different outcome.

A year of turbulence across a wide arc from AfPak to the Arab world, from Somalia to Nigeria, poses key questions to al-Qaida. The movement again commissions a report from its favoured consultancy, to which openDemocracy has exclusive access.

The tensions between Washington and Tehran are being further fuelled by naval exercises and discussion of strikes on Iran's nuclear facilities. This makes the absence of a direct communications channel all the more worrying.
