He made the remarks during a meeting with the families of “Martyrs of Security” in Imam Khomeini Hussainiyah, Tehran, on Sunday.
Ayatollah Khamenei said that the Zionist regime’s miscalculation should be thwarted.
“They (the Israelis) need to understand the power, determination, and innovation of the Iranian nation and its youth,” he added.
“How to convey this power and resolve of the Iranian nation to the Zionist regime is for our officials to determine, and what is in the best interest of the nation and the country should be done.”
The Leader further emphasized that Israel’s evil act should “neither be exaggerated nor downplayed.”
Ayatollah Khamenei also said that regarding the issue of confronting the Zionist regime, a major shortcoming is on the part of governments, nations, and international organizations such as the United Nations.
“What the regime did and is doing in Gaza and ... Lebanon is one of the most brutal war crimes,” he pointed out.
“The world must stand against them (the Zionists), governments must stand up, especially the Islamic governments.”
Helping Israel is among “the worst and biggest sins,” the Leader stressed, calling for the formation of a global political and economic coalition against the evil regime, and if deemed necessary a military one.
Meanwhile, Ayatollah Khamenei warned that a weak nation that cannot defend itself will naturally lose its security.
“The thing that maintains the security for a country is its national power; it is the strength of that country ... in all fields,” including science, economy, the possibility of defense, and weapons, he noted.
