Where is the real khalifah of the Muslims?

A comment on the videos circulating on Social Media related to Mirza Masroor Ahmad Qadiani shown as the Khaleefah or Caliph of the Muslims by Google/Wikipedia: "Obviously, Mirza Masroor Ahmad Qadiani is not our Khaleefah but who is it then? Where is the real Khaleefah of the Muslims?? The simple answer is, there is none as Khilafah doesn't exist. The last Khaleefah was expelled from Istanbul by the Secularist Mustafa Kamal on 28th Rajab, 1342 (3rd of March, 1924). Since then, the Muslim ummah is without a Khaleef for almost 100 Hijri years now. As per the consensus of the Sahaba (ra), Muslim ummah must not allow 3 days to lapse without appointing a Khaleefah over them. After 3 days, the whole ummah is sinful for not having the Bayah (Bayt) of a Khaleefah over their necks. The sahabah (ra) delayed the burial of Rasool Allah (swt) for almost 3 days, until Abu Bakr Siddeeq (ra) was appointed a Khaleef. Umar (ra) after he was gravely injured by an assassin, gave the top 6 Sahaba only 3 days to come up with the nomination and then appointment of a Khaleef over them and the entire Muslim Ummah. The penalty for not achieving this task within 3 days was death. The ullema deduced from these incidents that Muslims must not live in a situation where they have no Khaleefah over them for more than 3 days. But it's coming upto 100 Hijri years that this ummah is without a Khaleefah. What a calamity, subhan Allah. This yateem/orphaned Ummah has not seen a single day of peace, security and prosperity in the last 100 years. We have been divided into 55 plus Secular Nation States. Millions of our innocent women and children butchered by the wars caused either directly or indirectly by the colonialist powers. We are in the state of utter humiliation without a Khaleef who was supposed to unify our affairs and apply Islam as a deen over us. Without all this, Islam has been reduced to another religion like Christianity and Hinduism. What a calamity. It is a Fardh upon all Muslims to bring real Khaleefah back and we must all call and struggle for it. Not just by giving feedback to Google and Wikipedia to correct their pages but by raising this call with all the Muslims focusing especially on the influentials around us and by aiming this call towards places where Khilafah has the most realistic possibility to emerge again; places like present day Bangladesh, Pakistan, and Turkey etc. Become part of this single Ummah level global intellectual and political struggle before our time runs out. As per the hadith of Rasool Allah: "Whoever died without an Imam (i.e a Khaleefah), he dies a death of jahilyyah (pre-islamic times)". (Musnad Ahmed volume 4 page 96)".
