A Trump administration proposal to nationalize a portion of the nation’s wireless network in order to combat threats from China in 5G raises many technical, logistical and political concerns, including a fierce debate over the proper role of government in business.

The bottom line: The proposal calls for aggressive government involvement in the private wireless market, representing a significant shift in U.S. industrial policy that would hugely disrupt the business plans of America's largest telecom and technology companies.
