U.S. economic and political clout will decline over the next two decades and the world will be more dangerous, with food and water scarce and advanced weapons plentiful, U.S. spy agencies projected on Thursday.
The National Intelligence Council analysis "Global Trends 2025" also said the current financial crisis on Wall Street is just the first phase of a global economic reordering.
The U.S. dollar's role as the world's major currency would weaken to become a "first among equals," the report said.
The outlook is intended to inform U.S. President-elect Barack Obama of factors that will influence global events. It is based on a year-long global survey of experts and trends by U.S. intelligence analysts.
"The next 20 years of transition to a new system are fraught with risks," said the report, which was more pessimistic about U.S. influence and the potential for conflict than the last outlook for 2020.
Thomas Fingar, chairman of the intelligence council and deputy national director of intelligence for analysis, said harmful outcomes were not inevitable.
"It is not beyond the mind of human beings, or political systems, (or) in some cases (the) working of market mechanisms to address and alleviate if not solve these problems," Fingar told reporters. "We could have a better world in 2025."
China and India, following a "state capitalism" economic model, were likely to join the United States atop a multipolar world and compete for influence, the report said.
Russia's potential was less certain, depending on its energy wealth and internal investment. But Iran, Turkey and Indonesia were also seen gaining power.
A world with multiple power centers has been less stable than one with a single or two rival superpowers, and there was a growing potential for conflict, the report said.
Global warming will be felt, and water, food and energy constraints may fuel conflict over resources.
"Strategic rivalries are most likely to revolve around trade, investments and technological innovation and acquisition, but we cannot rule out a 19th century-like scenario of arms races, territorial expansion and military rivalries," the report said.
"Types of conflict we have not seen for a while - such as over resources - could reemerge," it said.
Global wealth was seen shifting from the developed West to the energy-rich Gulf States and Russia, and to Asia, the rising center of manufacturing and some service industries.
Global rich-poor disparities would grow, leaving Africa vulnerable to increased instability.
A reordering of the world financial system was happening faster than the report's authors envisioned, Fingar said. Last weekend's Group of 20 summit of advanced and major developing countries in Washington showed work had begun, he said.
A shift away from an oil-based energy system will be underway or complete by 2025. Better renewable technologies such as solar and wind power offer the best opportunity for a quick and low-cost transition, the report said.
There was a greater, but still small, risk of nuclear attack, based on spreading technologies and the weakening of international nonproliferation systems.
If Iran were to acquire nuclear weapons, Fingar said, that could set off an arms race in the Middle East, which is considered in the report as an "arc of instability."
The risk that militant groups would use biological weapons was greater than the risk of nuclear terrorism, the report said.
The appeal of terrorism could decline over the next two decades, particularly if Middle Eastern countries provide productive education and opportunities for their young people, the report said. But with a growing population, the pool of potential terrorism recruits is likely to be larger, and access to dangerous weapons will rise.
Dr. Mathew Burrows, the principal drafter for the Council report, told Haaretz on Friday that "it is not meant to be pessimistic, we actually talk about opportunities as well".
Presenting the report at the Foreign Press Center in Washington, Burrows also said that despite the numerous probems facing the U.S. in the international arena, he doesn't think it's going to affect the special relations with Israel. "Israel as well faces numerous challenges, but the relations are strong, and the American Interest in the Middle East dictates that they'll remain strong".
