The budget resolution held no one back for long, since Republicans increasingly use such resolutions as political propaganda rather than serious and bindingconstraints.
But much more is needed than the fragile discipline imposed by the Maastricht treaty and by the stability pact, such as bindingconstraints on budget laws of member states and institutions able to enforce them.
Which in turn means that published reserve numbers for any metal or mineral are not what we should use if we want to talk about binding resource constraints.
