With the Pacific Deterrence Initiative, the administration of US President Donald Trump showed his determination to deal with China militarily.

The US Senate Military Commission in early June passed the Defense Authorization Act (NDAA) in 2021, which contained an important additional provision that financed the Pacific Deterrence Initiative (PDI).

Experts say this is a move that demonstrates Washington's determination to deal with Beijing militarily.

Despite many tough announcements aimed at China over the past three years, President Trump has almost no move to deploy large-scale troops to the Pacific, an area considered by Washington to be a top priority.

Christian Le Miere, foreign policy advisor at strategic consulting firm Arcipel in the UK, said American politicians had a consensus on dealing with China after the outbreak of Covid-19.

"This amount only accounts for 0.2% of the total US defense budget expenditure. However, the additional budget for the PDI shows that Washington has political determination and solidarity in its policy with Beijing," Le said.

The purpose of the PDI is similar to the European Deterrent Initiative launched by the former administration of President Barack Obama in 2014. The European Deterrence Initiative (EDI) is proposed to "embarrass" Russia, reassuring intelligent allies.

Under the PDI initiative, the United States will seek to convert a small number of large bases near China into a series of smaller bases, but dispersed in a better position and have superior missile defense capabilities.

However, the biggest problem with the US right now is sending troops from other battlefields to the Pacific.

New conflicts and crises in the Middle East and Africa caused the United States to divert attention and resources into the Pacific, although the Trump administration has often taken a tough stance with China.

The White House boss is seeking to muster the Pacific with plans to withdraw troops from Afghanistan and Iraq, and consider reducing troops in Germany and Africa.

PDI is the first concrete step of the Trump administration towards a more realistic deterrent to China, but the bottom line is whether it will help reassure allies in the region.

Some allies such as the Philippines and Thailand have sought to ensure security by building warm relations with China, while South Korea has been insecure over threats of ending joint exercises and reducing its military presence.

"With Washingon, expressing determination and commitment will be PDI's key goal to prevent weakness in regional alliances after nearly a decade of pivot to Asia. However, the effectiveness of the initiative
