Well, if start with too many "if if if if" and we'll never reach any objective conclusion about this or any other subject. Let's go back to the real world for now, the world where there is no reasonable sign at all that they would have millions of Muslims desperately wanting to flock towards Hungary "if" (another if) they didn't do anything.
The real-world fact is that those Eastern European countries actually have NO significant problem with immigration at all, so it is baffling that it is a big electoral and political topic there, mainly as scapegoating was also very good for political profits in times of crisis (of economy, identity, political transition etc.). They all should have much more pressing and - more importantly - REAL, not based on "ifs", problems that they should be very concerned with before even thinking of considering immigration, let alone Muslim immigration, THE issue that decides elections and policies.
It's a secondary problem in their countries (actually, less problematic to the local demography than the extremely low fertility rates and the brain drain with high emigration rates among the youth), no matter how much these right-wing parties and leaders want to make a boogeyman and a big scandal about it to gain the favors of some gullible and faint-hearted voters.
Also, another fact is that, whether people like t admit or not, almost NOBODY dreamed of crossings oceans and continents to arrive in Europe and establish oneself in Hungary, Poland or, worse, Ukraine or Serbia. That's simply not what the immigrants plan, and the best proof for that is that the vast majority of the refugees and immigrants pass through Hungary and willingly leave: their destination is simply NOT there, period. There was, aren't and won't be any massive influx of immigrants who make everything to get to live there as in France, Germany or Sweden. Even in the worst scenario, they'd receive a moderate influx of a few thousands of immigrants per year, even if the EU quotas were established and respected.
Except for desperate war refugees who would accept living in any place free of the burden of war and persecution, the overwhelming majority of immigrants want better job opportunities and public services, and they are willing to risk everything in their nations only if they think they have a lot to gain from that perilous journey. No, most of them don't think Hungary or Poland are worth the risk, and those who reach those territories almost always want to get out of there and move to more developed and multicultural places, with or without Orban, with or without anti-immigration policies.
It baffles me that you and other people can't see that the immigration crisis is real, BUT IT IS NOT AN URGENT ISSUE in the likes of Hungary, Poland or Ukraine at all, and those who keep talking about immigrants and Islam and so on without any big, concrete and imminent risk posed by those things in their countries are just trying to divert people's attention from much more worrisome and direct INTERNAL problems of their countries. "If this, if that" is just not enough to make it such a big issue, especially when the evidences point to the fact that, sorry, but those countries are just not "that" interesting as a major target of economic immigration.
