A congressman involved with military innovation this week said the US must prove to Beijing that it can stop China if President Xi Jinping were to risk an invasion across the Taiwan Strait in an attempt to bring Taiwan under Chinese control.

If China invades Taiwan, the United States must realize that it cannot rely on the Taiwanese people to be the only fighters, as they were in Ukraine, Rep. Seth Moulton (D-Mass.) and co-chair of the congressional Future Defense Task Force said Tuesday at the Hudson Institute. Instead, American troops would need to be ready and committed.

Moulton said that Taiwan should have the required weapons, systems, and trained forces to delay the invasion long enough for the United States to overcome a blockade and come to its aid. In Ukraine, on the other hand, assistance is being provided across land, rail, and highway.

Moulton added that the late reactive approach worked for Ukraine, but it is not an option for Taiwan.

These tools, which Congress has authorized, including recruitment and retention flexibility and weapons systems development, have yet to be utilized efficiently by the services. At the same time, Congress has prevented the services from divesting themselves of legacy systems to invest in future technologies, making it more challenging to pay for future modernization.

There are “a lot of similarities in legacy motives” between Russian President Vladimir Putin’s unprovoked invasion of Ukraine and Xi Jinping’s threats to forcibly unite the self-governing democracy with the mainland.

The administration of Joe Biden provided military supplies and economic assistance to support Ukraine’s defense, relocate refugees, and impose harsh sanctions on Russian businesspeople and leaders.

The national guard proved its worth in repelling the Russian incursion, Moulton said. He said that many of its fighters were well-trained and had experience fighting Russian-backed separatists in the Donbas region since 2014. Kyiv took preparedness seriously, he added.
