I don't think anyone can be happy with the peace deal with Iran. Not because of anything the US or allies have done but because Iran will never stick to any agreement. As Trump said thye have made something like 10 agreements and the Iranians keep breaking the deal.
Just like with Hamas and other radical Islamists they vow never to submit and aim to wipe out Isreal and the west. Including Christians. So any peace deal is just following diplomatic proticols and we all know that none of this will make any difference.
Iran and its proxies have been inflicting terror on Isreal and the west for decades. People forget that the west was the targets only a decade or two ago. Remember 9/11, the 2004
Madrid Commuter Train Bombing, and the 2005
London transport bombings. As well as many smaller attacks on night clubs, buildings and public events. Don't forget many inhumane attacks on their own people and Muslims in many nations. Iran killed something like 10,000 people recently for protesting against the regimes control over their freedoms.
2025–2026 Iran massacres.
So this has been brewing for years and past governments have turned a blind eye. It was inevitable that the west with the EU were going to have to address this whether now or when it gets so bad that they cannot ignore it. If Iran managed to get a nuclear weapon then everyone knows they would use it without hestitation. They want a holy war against all who do not submit to their radical Islam.
So yes keep making deals and keep making the Iranians accountable when they break deals. They only understand one way which is force. If we don't deal with this then they will wipe out Isreal and then start attacking the west again. In fact they are already doing this with many radicals secretly plotting in western nations who were allowed to immigrate and import their toxic ideology.
In some ways the radical Islamists are winning the culture war. Never just mind Iran. Many westerners are taking up their cause and becoming radicalised against their own nations. They would rather side with terrorist than with their own free nations. In some ways the freedoms the west have given has allowed some to then try and bring down their own governments.
The difference is unlike the Iranian regime we don't wipe out 1,000s for protesting. But we should take a stand against those who want to destroy the west from within as this is only helping the Islamists who want to destroy the west anyway they can. Which includes spreading their vile and hate for the west.
