Puṣṭa Kṛṣṇa: The American soldiers, they were simply taking intoxication, hunting after prostitutes and running from the enemy.
Prabhupāda: And when they were attacked, they were running away. Because they are śūdras. How they can fight? They are not trained up as kṣatriyas. Huh? Anyone who is unemployed, let him become a soldier, but he cannot fight. That is not possible. Neither this class of men can have good brain to give direction to the society. The democracy means anyone can go to the government, and because he's not kṣatriya, his only business is how to get money so long he's on the post. Just like you did not like your President, Mr. Nixon. So that is the risk. If you keep the society in chaotic condition, any department—intellectual, administration, production—they'll be all topsy turvey, and there cannot be any peace in the world.
So this Vedic scheme, varṇāśrama, is very important scheme. If possible it should be introduced and taken up very serious. That is one of the items of Kṛṣṇa consciousness movement, to reestablish the institution of varṇa and āśrama. Not by birth, but by qualification. Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). Guṇa-karma, by quality. In India, the varṇāśrama is there, but it is not organized because the government does not take care. The government is imitating Western way of life, "There is no need of brāhmaṇa, there is no need of kṣatriya, simply śūdras." Everywhere this is the position, the śūdra population. Kalau śūdra sambhavaḥ: in this age everyone is a śūdra. So it doesn't matter everyone is born śūdra, but he should be trained up.
