I have being living for over 20 years in U.S. I have no idea what the
Bruxelles' Politburo things about OpenBSD but I can tell you that U.S. government agencies have full faith in the technical competence of U.S. companies (IBM, HP, Oracle, Google, Microsoft, and similar), and U.S. based open source projects (RedHat, Python etc), often sponsored by DARPA and similar agencies, to provide software solution for military and civilian use.
If there is a hole in Juniper or Cisco firewall it is there for the reason not because people are not competent to plug it. Also in U.S. any software product without large legal entity which can be sued in the case something goes wrong is essentially non usable except for the research purposes or a base for proprietary products.
