President Bola Tinubu, who is in charge of local superpower Nigeria, respects the overthrow across the boundary in Niger as a litmus test for a majority rules system in West Africa.
Having expected the chairmanship of local coalition Ecowas a simple three weeks prior, he was stood up to with a significant international strategy challenge when the military held onto power in Niger - an essential partner in the battle against aggressor Islamists unleashing devastation across a lot of West Africa.
Mr Tinubu had raised worries about the upsets in Burkina Faso, Mali and Guinea when he rose to Nigeria's administration in May, saying Ecowas expected to reinforce its territorial power to forestall further overthrows, and to battle the aggressors.
So when Niger's Leader Mohamed Bazoum was ousted by his official monitors last week, he answered quickly by meeting a highest point of West African pioneers at his official estate on Sunday.
The territorial coalition gave a final proposal to Niger's junta - hand back capacity to the chosen president in no less than a week or Ecowas would take "all actions important to reestablish sacred request".
Their statement added, "Such measures may include the use of force" and that military chiefs were to meet "immediately."
However Mr Tinubu's own triumph in February's official political decision is being tested in the courts by resistance competitors who guarantee the outcome was manipulated, he styles himself as a section in the liberal mission contrary to military rule in Nigeria during the 1980s.
According to Nigerian Institute for Security Studies (ISS) analyst Wole Ojewale, "I think he sees this [coup] as an affront to his democratic credentials, particularly at a time when he is holding the chairmanship of Ecowas."
All the more urgently, the overthrow has an immediate bearing on Nigeria. The two nations share a boundary which extends for more than 1,500km (930 miles), and they have solid social and exchange ties that date back to the pre-pioneer time when a lump of both were important for the Sokoto caliphate.
Their security is likewise interlaced. Aggressor Islamist bunch Boko Haram has done assaults in the two nations, with a tactical power - comprised of troops from Nigeria, Niger, Chad and Cameroon - battling them. The power's "key and specialized accomplices" incorporate the UK, US and France, with the last two having army installations in Niger.
While Niger represented around 4% of worldwide uranium yield in 2022, it is the world's seventh biggest maker of uranium and has the most elevated grade uranium mineral in Africa.
In a region where militant Islamists are active and Russia and the Wagner mercenary group are expanding their influence, neither Ecowas nor its Western partners would want the radioactive material, which is utilized in both civilian and military settings, to fall into the wrong hands.
After their upsets, Mali and Burkina Faso turned towards Russia, with the junta in Niger giving the feeling that it could move in a similar course.
Chad's chief Mahamat Idriss Déby Itno - who was placed in power by his own military after his dad was killed by rebel powers in 2021 - went to Niger on Sunday to ask the junta to notice Ecowas' final offer.
Chad isn't an individual from the provincial coalition, yet Mr Déby went to its gathering before on Sunday. He was thought to be in a good position to connect with the coup leaders and convince them to resign because he was a military strongman.
However, the junta has so far denied.
Instead, it has stepped up its rhetoric against Ecowas and the West, and thousands of its supporters supported the coup on Sunday in Niamey, the capital of Niger. Some of them went after the French consulate and waved favorable to Russian banners.
However, a survey conducted in 2022 by the reputable research organization Afrobarometer found that more than half of Niger's citizens were satisfied with the way democracy functioned in their country.
Of the 36 African nations surveyed, only Tanzania, Zambia, Sierra Leone, and Mauritania had higher democratic approval.
Nonetheless, 66% of those overviewed said that tactical men could intercede when chosen pioneers mishandled power. This is a contention that the people who mount overthrows, as well as their allies, frequently make to legitimize their activities.
Ecowas has been warned by the juntas in Mali and Burkina Faso not to use force in Niger because it would be a "declaration of war" and they would go to defend their fellow coup leaders. So military mediation chances gathering momentum into a full-scale struggle.
In any case, Ecowas has recently sent troops to various nations - including Liberia, Sierra Leone, Guinea-Bissau and The Gambia - either to assist with finishing nationwide conflicts, restore removed presidents or to compel out pioneers who would not acknowledge electing rout.
Even though its troops were occasionally accused of violating human rights, these interventions were carried out in accordance with its mandate to preserve "peace, stability, and security within the region."
Mr Ojewale isn't certain about whether the coalition has the tactical capacity to mediate in Niger - a huge dry country on the edge of the Sahara Desert - particularly when a large number of the nations that make it up, including Nigeria, are confronting their own security challenges.
He stated, "The few resources they have may be stretched thin."
