Wrong in so many ways.
First, there are two billion Muslims in the world so that's not a plausible argument. They literally couldn't fit into Pakistan, which in any case is not the birthplace of Islam, whereas Israel is the homeland of Judaism. And there are still not as many Jews in the world as there were before the Shoah - so that too is another reason why wanting a country which could be a refuge for Jews is a reasonable aim. Muslims have dozens of muslim-majority countries to flee to, if ever there really was a determined attempt to exterminate muslims such as happened with the Jews.
And in fact Pakistan was originally founded on the basis of securing a homeland for the Muslims of the Indian subcontinent, not unlike Israel, except without the historic background to justify it.
It is also an Islamic republic: the 1973 constitution, brought in after Pakistan's first ever general elections, declared Pakistan to be an Islamic Republic and Islam to be the state religion. It also stated that all laws would have to be brought into accordance with the injunctions of Islam as laid down in the Quran. Hence non muslim minorities have been arrested for eating in public during Ramadan, and women are forced to have a male guardian and cannot leave the country without permission etc.
But right from Pakistan's beginnings, the president of the Muslim League said that Pakistan would bring together all Muslim countries into a pan-Islamic entity called "Islamistan". He believed that Pakistan was a Muslim state but not yet an Islamic state, and that it could become an Islamic state after bringing all believers of Islam into a single political unit. But they wanted all the land where Muslims lmived - imagine if the Jews had insisted on including Poland, Ukraine and Lithuania? Plus Yemen and Iraq and much of North Africa: that's what Pakistan wanted to do.
More recently, Pakistan bombed a hospital in Kabul, killing unknown numbers - and all of that just gets a shrug in the UK and the west in general.
Proving, I suspect, the OP's argument. Criticising those Islamic rules mentioned above, even in the UK could get you a possible death sentence (the Batley teacher and his family are still in hiding more than 5 years after he dared show a cartoon of Muhammed) but people are free to say whatever they like about Israel - as they should be. But they should also remember that they can say whatever they like about Yahweh without having to hide for the rest of their lives.
