01About This Special Issue

National security needs to be studied, and learners must have the incentives to do it as thoroughly as it is worth and is paid. A system for studying national security is needed - permanent and "lifelong". Strategies based not on resources but on goals, are no longer looking for such tasks that fit our knowledge, but are looking for such knowledge that responds to the tasks to be solved by the security system.

Aims and Scope:

  1. education
  2. science
  3. security
  4. strategy
  5. knowledge
  6. innovation
