no this should'nt b abt the existence of leaf village, bt should b abt the sacrifices they made for their country. No doubt minato sacrificed a lot, bt jst bcoz the village was at greater danger due to d fox at that time dsn't mean that minato sacrificed more........ I think itachi sacrificed more, coz he nt only killed his entire clan, bt also agreed to keep quiet nd b portrayed as a criminal nd was hunted down fr his entire life, moreover he decided to die by his brother's hand so that his brother could live in peace nd unlock a new power that wud protect him, so itachi sacrificed everythng that was dear to him, to protect his village.......
