Monday's vote on the renewal of the Trident 'monstrosity', just 18 miles from Largs, has sparked a wave of new protests.
And organisers hope that the show of solidarity at a hastily arranged protest in Largs will show that old-fashioned word of mouth can be the catalyst for some form of change, despite the likelihood of a vote favouring renewal at Westminster.
Tim Cowan, who helped organise the Largs event in the Main Street on Saturday, said: "We had around 50 people at the protest, which, given the short notice and weather, demonstrates that even in smaller communities like Largs there is real anger about Trident.
"While people may see submarines on the Clyde, there are still many who don't fully appreciate the scale.
"That is why we read poems about Hiroshima, to show the impact of one nuclear weapon and really see the level of atrocity.
"We have had the terrible events in Nice, where around 100 civilians have been killed. In Hiroshima, 300,000-plus died.
"We don't really have the Cold War anymore, the threats are climate change and terrorism, which does not involve nation states.
"I think everyone here is united in the view that it is just a moral monstrosity."
While the campaign has a strong online base, Tim said that simply talking to others about the issue could be just as valuable.
He said: "We want people to go and speak to others. We are a broad coalition, from CND and trade unions to faith groups and the general community.
"While the vote is likely to go through, this may just be the start of something. Write to MPs and MSPs. Go to the Scrap Trident site at scraptrident.org, join a local CND branch, do some research and, once again, talk to others."
