Rahul Tandon looks at changing attitudes to defence spending following Russia's invasion of Ukraine. There have been new funding commitments from countries like Germany, while Sweden and Finland now want to join NATO, but what's the true cost? We speak to Estonia's defence minister Kalle Laanet about his country's growing military budget, and German member of the European Parliament Viola Von Cramon Taubadel on her country's decision to spend more. Dr Diego Lopes Da Silva, a researcher with the Stockholm International Peace Research Institute, says global spending reached a record level of $2 trillion in 2021, before the invasion of Ukraine. Steven Zaloga, a military analyst at the Teal Group, explains the role of cutting edge drone technology, and Allison Pytlak from the Women's International League for Peace and Freedom discusses the human cost of conflict.
