“If this alien becomes an enemy (as all alien friends may) then he is utterly disabled to maintain any action, or get anything within this realm.”
“… the law recognises a state of peace and a state of war, but .. it knows nothing of an intermediate state which is neither the one thing nor the other – neither peace nor war.”

“I promised to let you have a reply to the question put in the House on 13 May about the mechanism for informing the House if we were legally in a state of war with Argentina. As you will be aware, the military and naval operations which we are currently conducting in the South Atlantic are being carried out in exercise of the United Kingdom’s inherent right of self-defence recognised in Article 51 of the United Nations Charter, following the flagrantly unlawful Argentine invasion and occupation of the Falkland Islands. The prime objective of these operations is to secure the withdrawal of Argentine forces from the Islands. In the circumstances, we do not consider that there exists a state of war between this country and Argentina. However, should Argentina formally declare war against the United Kingdom, an immediate statement would be made to the House.”
“We have not been at war with the Federal Republic of Yugoslavia. The application of international law to an armed conflict is not dependent upon the existence of a state of war between the parties.

I do not propose to be the first to lay down a definition of ‘war’ in a so called technical sense.”
“Authority to use force against Iraq derived from the combined effect of UNSCRs 678, 687 and 1441; and all of those resolutions were adopted under Chapter VII of the UN Charter, which allows the use of force for the express purpose of restoring international peace and security.”
