A question about Non Muslims

Non Muslims cannot preach their religion in a Muslim country but a Muslim should be allowed to do so in a non Muslim country. Also if the non Muslim country doesn’t allow Muslims to preach Islam there, Muslims have a right to start a war against the country. Why is that so? > Thus what is meant by the passage in Tafsir Uthmani, is that if a country doesn’t allow the propagation of Islam to its inhabitants in a suitable manner or creates hindrances to this, then the Muslim ruler would be justifying in waging Jihad against this country, so that the message of Islam can reach its inhabitants, thus saving them from the Fire of Jahannum. If the Kuffaar allow us to spread Islam peacefully, then we would not wage Jihad against them.
