At a hearing today, U.S. Senator Deb Fischer (R-Neb.), a senior member of the Senate Armed Services Committee, questioned senior intelligence officials about the growing threats posed by Russia, China, and North Korea — including an alarming nuclear buildup and efforts to disrupt critical U.S. infrastructure.

During the hearing, Senator Fischer questioned the Director of National Intelligence Avril Haines and Defense Intelligence Agency Director Jeffrey Kruse about dangerous new capabilities from U.S. adversaries and the alarming increase in the nuclear arsenals of China and Russia.

Senator Fischer stressed the importance of maintaining U.S. deterrence. In April, Senator Fischer introduced the Restoring American Deterrence Act to overhaul U.S. nuclear preparedness and enact key updates to America’s strategic posture.

Senator Fischer also raised the alarm about the risk of cyberattacks by China against critical U.S. infrastructure and attempts by Chinese state-sponsored cyber actors to pre-position themselves on networks to disrupt functions.
