A War Cabinet is committee formed by a government in time of war. It is usually a subset of the full executive cabinet of ministers. It is also quite common for a War Cabinet to have senior military officers and opposition politicians as members.
The kind of war we must fight against this sort of enemy is very different from what we faced in 1938, and yet the neocons, old soldiers all (albeit not of the uniformed type), are preparing to fight the last war.
We "undermined" the war effort: we made the U.S. cut and run." But this is akin to a madman standing on the edge of a precipice, insisting on his power of flight.
In any case, wars always rearrange the political landscape: liberals become conservatives and internationalists become "isolationists" (and vice versa), and people switch parties, break old allegiances, and craft new alliances.
The inaugural meeting of the WarCabinet was held on 27 September 1939 at Victoria Barracks in Melbourne, in a room at the rear of the first floor of the northern wing, which had been completed in 1916 as an addition to the main building (A Block) on St Kilda Road.
It was agreed that the WarCabinet, which should include such Ministers as the Prime Minister should direct, together with such Ministers as from time to time were coopted, should deal with all matters in relation to the conduct of the war other than matters of major policy.
WarCabinet meetings were held at Victoria Barracks, Melbourne, and in the Cabinet room adjacent to the prime ministerial suite at Parliament House, Canberra.
