Is that name attached to the quote about Greece a real person? When I google him, all that shows up are four pictures of some diplomatic-looking guy from the EU, but there is no text at all about him. With a name that absurd, you'd expect lots of results to pop up. Also, Nixon really shouldn't be one to talk.
Even if you gave hints for the names of the quoted people, the percentage of quiz takers who'd get them would remain really small I think. But a hint such as their initials might be useful? I was a bit surprised that Churchill didn't say any of those things.
- Erich Ludendorff (without 'von')
- George Turberville (instead of Turbeville)
- Jeroem Dijsselbloem (without 'rumbic')
There's a quote commonly attributed to Charles de Gaulle that goes: "Brazil is not a serious country."
The quote is actually from a diplomat, but summarizes well Brazilian politics.
