President Donald Trump has announced the construction of a vast new missile defense system, dubbed the “Golden Dome,” designed to intercept ballistic, hypersonic, and space-based threats. Modeled after Israel’s Iron Dome but scaled to a global level, the program is projected to cost $175 billion and be completed by the end of Trump’s current term in 2029.

Canadian Prime Minister Mark Carney confirmed on Wednesday that Ottawa is in active talks with Washington about joining the project. “We are conscious that we have an ability, if we so choose, to complete the Golden Dome with investments and partnership,” Carney said following a Cabinet retreat, adding that participation would be assessed from a national security standpoint.

Strategic Shield With Space Ambitions

The Golden Dome will incorporate space-based interceptors and sensors capable of neutralizing missile threats from hostile nations — or even those launched from orbit. Trump stated: “Once fully constructed, the Golden Dome will be capable of intercepting missiles even if they are launched from the other side of the world, and even if they are launched from space.”

The system will be led by U.S. Space Force General Michael Guetlein, and construction has already begun under initial funding of $25 billion. Trump emphasized, “This is very important for the survival of our country,” pledging to “complete the job that President Reagan started” with the Cold War-era Star Wars initiative.

Allies and Adversaries Respond

Canada’s interest in joining the U.S.-led shield comes amid heightened concern over growing missile capabilities in Russia, China, and North Korea, and a stated desire to modernize North American defense cooperation. Trump claimed Canada had reached out proactively to participate, and both militaries have long discussed ballistic missile defense cooperation.

However, the move has drawn sharp rebukes from Beijing and warnings from arms control experts. China’s Foreign Ministry condemned the plan, saying it “violates the principle that no country’s security should come at the expense of others” and “heightens the risk of space becoming a battlefield.”
