The IfS is complementary to the EU activities under other thematic and geographic instruments in third countries.Subdivided into a short- and a long-term component, its aim is threefold, as articulated in the IfS Strategy Paper 2007–2011: • to ensure an effective, rapid, flexible and adequately funded initial response to situations of political crisis or natural disaster in third countries (short-term);• to develop, longer-term Community actions to counter global and trans-regional threats arising from organised crime, trafficking, proliferation of chemical, biological, radiological and nuclear (CBRN) materials and agents and also threats to critical infrastructure and public health, while at the same time contributing to broader Community development and external policy objectives; (priorities 1 & 2, long-term);• to set up longer-term capacity building measures aimed at strengthening international organisations and nonstate actors with a crisis prevention or response mandate (priority 3, long-term).
