A leading House Republican believes the Biden administration’s defense policy of “integrated deterrence” is deeply flawed after it failed to deter Russia from invading Ukraine as the Pentagon touts the strategy to deal with China.

Rep. Mike Gallagher, a Wisconsin Republican who got the top U.S. general in Europe to admit this week that Western efforts to deter Russian leader Vladimir Putin failed, has leveled repeated criticism at the concept of integrated deterrence, which has been touted by Secretary of Defense Lloyd Austin for a year and which is at the core of the administration’s 2022 National Defense Strategy.
