While violence and destruction is strongly discouraged in Buddhism, it is ok for a ruler or government of a country that adheres to Buddhist principles, to establish police and armed forces to:
Please see Pali sutta quotes below.
However, what about the hypothetical case of Buddhists being persecuted in non-Buddhist lands? Buddhists in this case, should not bear arms and become freedom fighters or terrorists, as that is against the first precept and also other teachings e.g. removing mental aversion.
In this case, persecuted Buddhists should either leave the country (as what the 14th Dalai Lama had done in March 1959) or pursue peaceful legal means of action (as what Mahatma Gandhi or Martin Luther King had done) which could include petitions and letters to government officials and elected representatives, statements on media etc.
From DN 16:
"What have you heard, Ananda: do the Vajjis duly protect and guard the arahats, so that those who have not come to the realm yet might do so, and those who have already come might live there in peace?"
"I have heard, Lord, that they do."
"So long, Ananda, as this is the case, the growth of the Vajjis is to be expected, not their decline."
From DN 26:
‘But sire, what are the noble duties of a wheel-turning monarch?’
‘Well then, my dear, relying only on principle—honoring, respecting, and venerating principle, having principle as your flag, banner, and authority — provide just protection and security for your court, troops, aristocrats, vassals, brahmins and householders, people of town and country, ascetics and brahmins, beasts and birds. Do not let injustice prevail in the realm. Pay money to the penniless in the realm.

This is a good question and I pondered on this too. My conclusion is that it is not possible for invaders to concur with a Dhammic nation. Perhaps Tibet was concurred due to the drawbacks of the Mahayana religion. Perhaps in China, they persecuted the Muslims due to the drawbacks of Islam. (By the way, I am not endorsing any of these) If we follow true Buddhism, nobody can concur with us. According to my present understanding of Dhamma, nobody will be able to shake my faith. But I am not sure whether I will be able to pass that to the future generation.
