I do not know your level of education, but you seem to ignore all the facts and only report what you hear in the news.
Reality is bigger than that, to give you an example, the US and Israel can not dare attack Iran, it is just too powerful for them in any way, air, land or sea, ask or rather read what the American experts know and say... and even if they choose to use the ultimate nuclear option, not one single country in the Area will allow them, just because of the radioactive fallouts, let alone the promesses that Chinees and Russian highest ranking General have made to start WW3 with the States and Europe if Iran is attacked, not for their particular friendship or love for Iran but for the sake of their economies and the world economy, so indeed NATO can call Iran dangerous, you know now why, it is Europe's an American frustrations...
Apart from that the Iranian supremacy in the Persian golf and around it, it can infringe some too heavy losses on NATO that can not be acceptable for Europe and the US, like destroying completely the 5Th US fleet and any other fleet that will show up around. We are not talking about the madness of the thought of invading Iran, NATO will need to have 200 million soldiers to be able to win completely a conventional war against the 20 million (minimum) Iranian Armed forces. So please learn about history, warfare and facts and than talk tough,Netherlands won't stand one day on its own against Iran in the Persian Gulf.
