Most political leaders have social media accounts, as do many ministries of foreign affairs. These accounts can provide a useful platform for urging your government to ratify the Treaty on the Prohibition of Nuclear Weapons, or for asking questions about your country's progress towards ratification. Check here whether your government is active on social media.

Here are some ideas for posts directed at your government:

• "The Treaty on the Prohibition of Nuclear Weapons was adopted at the United Nations in 2017 with the support of 122 countries. Will [country] ratify it soon?"
• "Nuclear weapons pose a unique existential threat to humanity. [Country] should ratify the 2017 Treaty on the Prohibition of Nuclear Weapons without delay."
• "Why has [country] not yet ratified the 2017 Treaty on the Prohibition of Nuclear Weapons? This landmark treaty will make us all more secure by helping to eliminate the world's worst weapons."
