Washington: Defense Secretary Jim Mattis said Friday that America is facing "growing threats" from China and Russia, and warned that the US military's advantages have eroded in recent years.
Mattis' assessment came as he unveiled the Pentagon's vision for the future detailed in a document called the National Defense Strategy.
"We face growing threats from revisionist powers as different as China and Russia, nations that seek to create a world consistent with their authoritarian models," Mattis said.
"Our military is still strong, yet our competitive edge has eroded in every domain of warfare – air, land, sea, space and cyberspace – and is continually eroding," he added.
President Donald Trump and his administration worry that the vast US military force is feeling the effects of years of budget shortfalls and atrophy, and needs a full reboot to restore it to an idealised strength.
Blueprint for the future
Part wish list, part blueprint for the coming years, the Pentagon's national defense strategy seeks to increase the size of the military, improve its readiness and work with allies – all while operating across multiple theaters including in Europe, West Asia and Asia.
"This strategy establishes my intent to pursue urgent change at significant scale," Mattis wrote in the introduction to the strategy.
"We must use creative approaches, make sustained investment and be disciplined in execution to field a Joint Force fit for our time, one that competes, deters and wins in this increasingly complex security environment."
The announcement sparked a backlash from Russian foreign minister Sergei Lavrov, who branded the new US strategy as "confrontational."
"It is regrettable that instead of having a normal dialogue, instead of using the basis of international law, the US is indeed striving to prove their leadership through such confrontational strategies and concepts," Lavrov told a news conference at the United Nations.
Elbridge Colby, the US deputy assistant secretary of defense for strategy and force development, told reporters that Mattis's strategy seeks to deal with the "erosion" of America's military advantage.
"What it is recognising is that China and Russia in particular have been assiduously working over a number of years to develop their military capabilities to challenge our military advantages," he said.
South China Sea threat
The new defense strategy follows on from Trump's national security strategy that he released last month which, similarly, highlights the role of China and Russia in the global security environment.
"China is a strategic competitor using predatory economics to intimidate its neighbors while militarising features in the South China Sea," Mattis wrote.
"Russia has violated the borders of nearby nations and pursues veto power over the economic, diplomatic and security decisions of its neighbors," he added, while also pointing a finger at Iran and North Korea for their threats to peace.
The two countries reacted furiously to Trump's security strategy, with Beijing accusing Washington of having a "Cold War mentality" while Moscow denounced its "imperialist character."
Trump's security strategy contrasts with the friendly nature of his first state visit to Beijing in November, when he received a lavish welcome and repeatedly praised President Xi Jinping.
One of the biggest criticisms inside the Pentagon and on Capitol Hill is that the US military is suffering from a lack of readiness, where troops and gear are not getting the training or maintenance they need.
Mattis said the United States must be ready to fight a war.
"The surest way to prevent war is to be prepared to win one," he said.
"Doing so requires a competitive approach to force development and a consistent, multiyear investment to restore war fighting readiness and field a lethal force."
Pressure on European allies
Mattis' strategy also calls for greater coordination with allies, who Trump on the campaign trail lambasted for not doing enough to share the burden of defending the post-World War II order.
"We expect European allies to fulfill their commitments to increase defense and modernisation spending to bolster the alliance in the face of our shared security concerns," Mattis said, in reference to NATO countries paying more into their defense budgets.
Republican senator John McCain, who chairs the powerful Senate Armed Services Committee that helps oversee the Pentagon, welcomed Mattis's strategy for getting "the big decisions right."
"A new era of great power competition has emerged, and this strategy prioritises that reality," he said in a statement.
The document makes no mention of climate change, which under former president Barack Obama was recognised as a national security threat. Trump has claimed climate change is a hoax and pulled the US out of the historic climate accords in Paris.
