The Defence of the Nation and it's interests is a permanent mandate of Government, it has no higher duty.
If the Government cannot protect the state then how can it protect you? If it cannot, or will not protect you what right does it have to ask you to serve it, to obey it's laws or pay tax? We give up freedoms collectively in return for the protection of the Government. It is a trade off, but the Government must at all times uphold it's part for this to work. We expect not that we are totally safe at all times but that the Government and the institutions of government are committed to doing their duty towards us to the best of their ability. That we can expect a reasonable measure of safety and security.
Winston Churchill said this to the British House of Commons on the 12th of November, 1936:
"I have heard it said that the Government had no mandate for rearmament until the General Election. Such a doctrine is wholly inadmissible. The responsibility of Ministers for the public safety is absolute and requires no mandate. It is in fact the prime object for which Governments come into existence."
