Why couldn't Dronacharya defeat Arjuna?

 Dronacharya was repeatedly overpowered and countered by Yudhishthira let alone Arjuna.

He failed to capture Yudhishthira and proceeded to assault drupada soldiers.

• O descendant of the Bharata lineage! He released the aindra and prajapatya weapons. He wished to kill the son of dharma and was devoted to ensuring your son’s welfare. The lord of the Kurus possessed the gait of an elephant and a lion. He was broad in the chest and his eyes were large and red. His energy was not inferior. He invoked the mahendra weapon and destroyed those weapons. On seeing that his weapons had been destroyed, Drona was overcome with anger. Wishing to destroy Yudhishthira, he unleashed the brahma weapon.Everything was covered in darkness and we could see nothing. O lord of the earth! All the beings were full of great terror. O Indra among kings! On seeing that a brahmastra had been invoked, Yudhishthira, Kunti’s son, used a brahmastra to counter it. At this, all the foremost of warriors praised those bulls among men. ‘“Drona abandoned Kounteya and attacked Drupada’s soldiers.

Arjuna countered every weapon of Dronacharya even while extremely holding back against him

• Whenever Drona tried to do something to defeat Kunti’s son, he was swiftly nullified by the striving Pandava. Drona could not establish his superiority over Pandava in any way. The one who was skilled about the motions of weapons then invoked special weapons—aindra, pashupata, tvashtra, vayavya and varuna. However, as soon as these were released from Drona’s bow, Dhananjaya destroyed them. When his weapons were duly destroyed by Pandava’s weapons, Drona released supreme and divine weapons towards Partha. However, every weapon that was invoked with a desire to vanquish Partha, was duly destroyed by Arjuna with another weapon. When those weapons, including the divine ones, were duly destroyed by Arjuna, Drona honoured Arjuna in his mind.

Partha invoked aindastra to defeat Bhisma , karna , Drona and ashwatthama on 9th day all together . He was way too powerful for Kauravas

Why was it so crucial for Krishna and the Pandavas to defeat Jarasandha before attempting the Rajasuya sacrifice?

If Pandavas had faced Magadh army under emperor Jarasandha’s rule, they would've been effortlessly crushed like bugs.

Krishna himself along with Balarama, Satyaki, Pradyumna and whole of Yadavs combined couldn't do anything against Magadh's full might under Jarasandha..

He had unique boon from Rishi Chandakaushik to be invulnerable to weapons. 2 of his army generals named Hamsa and Dimvaka had same exact boon. In addition to this he gained many boons from Shiva which helped him conquer all countries in the contemporary world barring Hastinapura and Dwaraka. Hastinapura was spared due to Bhishma and Dwaraka was setup in Mountainous regions inaccessible to him.

Krishna to Yudhistira: -

It behoveth thee, O Bharata, to establish thy empire over all the Kshatriyas. But this is my judgment, O king, that thou wilt not be able to celebrate the Rajasuya sacrifice as long as the mighty Jarasandha liveth. By him have been immured in his hillfort numerous monarchs, like a lion that hath deposited the slain bodies of mighty elephants within a cave of the king of mountains.

..

By defeating the kings with their troops and bringing all of them as captives into this city, he had swelled its crowds enormously. We also, O king, from fear of Jarasandha, at one time had to leave Mathura and fly to the city of Dwaravati.

If, O great king, thou desirest to perform this sacrifice, strive to release the kings confined by Jarasandha, as also to compass his death. O son of the Kuru race, otherwise this undertaking of thine can never be completed. O thou foremost of intelligent men if the Rajasuya is to be performed by thee, you must do this in this way and not otherwise.

Further he stated that Jarasandha is too tough to be beaten in a war, even by Dev's and Asuras (obviously a hyperbole). And therefore be subdued in a personal combat where his army or allies won't interfere.

He is incapable of being vanquished in battle even by all the celestials and the Asuras (fighting together). We think, however, that he should be vanquished in a personal struggle with bare arms. In me is policy, in Bhima is strength and in Arjuna is triumph; and therefore, as prelude to performing the Rajasuya, we will certainly achieve the destruction of the ruler of Magadha. When we three approach that monarch in secret, and he will, without doubt, be engaged in an encounter with one of us.

From fear of disgrace, from covetousness, and from pride of strength he will certainly summon Bhima to the encounter. Like death himself that slays a person however swollen with pride, the long-armed and mighty Bhimasena will effect the destruction of the king.

That could be mythological reasoning. Realistically, Jarasandha simply could've been an unparalleled military intellect under whose command Magadh empire was unbeateable.

Jarasandh by himself was merely immune to weapons but was vulnerable to defeat in physical combat. But under his leadership, Magadh was Strongest military force in that era.

Which Indian king first time defeated Alexander?

 Porus (Puru or Purushottama), the ruler of the Paurava kingdom, is the Indian king who famously faced Alexander the Great.

🌊 The Battle of the Hydaspes (326 BCE)

Alexander’s forces clashed with Porus’ army on the banks of the Hydaspes River (modern-day Jhelum River in Pakistan). This battle marked a significant turning point in Alexander’s Indian campaign.

🐘 Porus’ Valiant Resistance

Porus, with an estimated 20,000-30,000 soldiers and 300 war elephants, faced off against Alexander’s 40,000-strong army. Despite being outnumbered, Porus’ forces put up an incredible fight.

Although Alexander’s forces ultimately won the battle, Porus’ bravery and strategic tactics impressed Alexander. Alexander was so impressed that he:

1. Restored Porus to his throne 👑
2. Granted him additional territory 🌍
3. Formed an alliance with Porus 🤝

🏆 Why is Porus Considered the Victor?

While technically defeated, Porus achieved a moral victory by:

1. Inflicting heavy casualties on Alexander’s forces 💥
