MPs voted in 2016 in favour of building submarines for a new nuclear weapons system to replace the current one, Trident. But all the facts stack up against nuclear weapons – and they continue to do so, irrespective of this shameful vote.
CND has calculated that replacing Trident will end up costing at least £205 billion. This is an appalling waste of money. Cancelling Trident replacement would mean we could invest billions in the NHS, our education system or new homes.
In terms of national security, nuclear weapons are irrelevant. The UK government’s own National Security Strategy identifies the real security threats we face today as terrorism, cyber-attacks and the consequences of climate change. Trident would be useless in dealing with these.
Nuclear weapons have no legitimate purpose: their use would be illegal under almost every conceivable circumstance, as huge numbers of civilian casualties would be unavoidable.
Preventing Trident replacement remains an urgent priority for CND. We want to see a world without nuclear weapons, and stopping Trident is an essential part of that process.
