Germany.
The country was designed to be incredibly hard to takeover from the inside.
Central government is weak, even if AFD would takeover the chancellorship there are few measures that would immediately allow them to intervene in the federal states or „Länder“, much much less than in the US e.g. unless there is war there is no way to use the military to force compliance.
You would have to take over the country 17 times, and since the elections are not synchronised you would have to convince everybody all the time that this is good idea.
Individual German federal states could be taken over much easier, Thuringia probably will be the first in 2028.
The biggest weakness than is that the legal prosecution on German federal state level is under control of the executive and could be used to prosecute political adversaries.
But if this goes to far the remaining parts of the country could vote to takeover the executive if there was a breach of the constitution.
