A- Obviously the soil around this magnificent tree is now compacted due to growth of roots that occupy the space pushing the soil apart. there is a simple technic to loosen the soil by forcing high pressure air of around 500 to 1000 psi through a thin steel pipe rammed in to the ground around the tree . Number of holes could be 50 or 100 depending on the estimated where about of the root system. This operation will loosen the ground and create space for the enriched solution of water and required nutrients to be injected near the roots. This procedure is not expensive at all and simple that can be carried out as soon as possible. All needed is a good compressor and a needle shaped steel pipe designed to be driven in to the soil about 2 meters.

B- The oldest country is Iran without any doubt. please go to Wikipedia and search the countries history and their age of existence. The list is complete and documented.

There is no difference between Persia and Iran. That’s the mistake the western people usually make. Persia is a part of Iran, located in south. When in 550 B.C. Cyrus defeated Medes, the Persian Empire was established. Since then the non-Iranians called the land Persia because the Akamenids (like Cyrus) came from Persia (now pronounced Fars because the Arabs who invaded Iran in 7th century could not say P). This way of calling Iran was originated from the Greek historians like Herodotus. The Iranians (or Persians, no difference) have never called the whole land Persia. In 1936 the Iranian government changed the official name of the country from Persia to Iran. because the country included many races other than Persians. The goal was to create more unity. This is a wrong way of thinking. According to you, the name of the old country, nation and culture is Persia, so there has never been a nation/state like Iran. This is like you say there is no Nippon (the name the Japanese call their country) in the world because there is Japan. I think the problem is originated from the word “modern”. If this word means ten years, then we can erase all the history.
Finally, I would like to add that the word “Iran” have existed in the documents remaining from the first millennium B.C.

I am talking about the modern nation-state that is today termed “Iran”, which only goes back about 500 years (from your first link, see “III – From Safavids to Modern Iran”)

If he/she lives in Iran today, then I guess he is. Such is what happens when borders and politics change.
