Trump pledges ‘greatest military build-up in US'

US President Donald Trump said he would make a massive budget request for one of the "greatest military buildups in American history".

Trump used remarks to the Conservative Political Action Conference (CPAC), an organization that gave him one of his first platforms in his improbable journey to the US presidency, to defend his unabashed "America first" policies.

Ahead of a nationally televised speech to Congress, Trump outlined plans for strengthening the US military, already the world's most powerful fighting force, and other initiatives such as tax reform and regulatory rollback.

He offered few specifics on any initiatives, including the budget request that is likely to face a harsh reality on Capitol Hill: At a time when he wants to slash taxes for Americans, funding a major military buildup without spending cuts elsewhere would add substantially to the US budget deficit.

Trump said he would aim to upgrade the military in both offensive and defensive capabilities, with a massive spending request to Congress that would make the country's defense "bigger and better and stronger than ever before."

"And, hopefully, we’ll never have to use it, but nobody is going to mess with us. Nobody. It will be one of the greatest military buildups in American history," Reuters cited Trump as saying.
