Israel new now
I think you meant to ask "Is Israel a new country now?"
Israel declared its independence on May 14, 1948, and it has been a sovereign state since then. However, the concept of a Jewish homeland in the region dates back thousands of years, and the modern Zionist movement, which aimed to establish a Jewish state in Palestine, began in the late 19th century.
The State of Israel was established after the end of World War II, when the international community, led by the United States, recognized the need for a Jewish homeland to provide a safe haven for Jewish survivors of the Holocaust. The United Nations voted to partition the British Mandate of Palestine into separate Jewish and Arab states, with Jerusalem to be administered by the UN. The Jewish Agency, led by David Ben-Gurion, declared the establishment of the State of Israel on May 14, 1948.
Since then, Israel has developed into a modern, democratic country with a thriving economy, a strong military, and a rich cultural heritage. It has also faced numerous challenges, including conflicts with its Arab neighbors, the ongoing Israeli-Palestinian conflict, and security concerns.
So, to answer your question, Israel is not a "new" country in the sense that it was established recently. However, it continues to evolve and grow as a nation, and its history and identity are still being shaped by its people and its experiences.
