当看到三岁的叙利亚难民Alan Kurdi尸体的照片时，谁不感到痛心呢？Kurdi和他的家人上周试图偷渡欧洲时，他和他的母亲Rehan，哥哥Ghalib一同溺亡。

那张他冰冷的尸体被冲上土耳其海滩，天使般的面容被埋在沙中的照片，使西方世界警醒到中东的难民危机正演变为大量流离失所的难民为逃离祖国战争而到欧洲寻求庇护。

当时Alan的父亲Abdullah试图营救他的妻子和儿子们，但却只能眼睁睁地看着摇晃的载着亲人们的小渔船被汹涌的海浪打翻并卷走。 这一幕，让天下的父母亲都如Alan的父亲一般痛心疾首。

Abdullan的妹妹Tima Kurdi，即小Alan的阿姨，是一位二十岁居住在温哥华市郊高贵林的加拿大居民。她是通过网上的照片才得知她心爱的小侄子死于非难。

这个家庭巨大的损失使每一位加拿大人都重新审视本国是否已采取足够措施来帮助中东和北非地区脆弱和无辜的难民。

尽管如此，我们永远都应该用理智而不是情感来制定政策。

源于根深蒂固的道德驱动力，包括加拿大在内的一些西方国家都有缓解叙利亚和利比亚（以及其他国家）难民们的苦难的强烈愿望，但我们必须记住，在过去的一年里，ISIS一直在威胁要挑起大规模的难民迁移，以达到掩盖其将恐怖分子渗透到西方国家的目的。

西方民主国家和他们的人民非常愿意敞开国门来援救难民，甚至可以说这种愿望是融合在他们的DNA中的，但因此就盲目的打开国门是鲁莽和不可取的。

ISIS的组织者们希望利用我们急于帮助那些不幸及受伤害的庇护寻求者的同情心而降低我们的防卫（和我们在边界上的壁垒）。

为什么他们不利用现在的危机，不管是不是他们引发的，来将他们的人员偷渡到西方世界？归根结底，就算我们不认为我们在与ISIS对战，这些穆斯林极端分子也会认为他们是在与我们对战。

由此造成的悲剧是触目惊心的。

经历了四年内战的叙利亚，以及遭受更长时间不稳定局面的利比亚，先后有数百万人被迫离开他们的家园，逃离至本国或临近国家的难民营中。随着难民的增多，这些营地变得过度拥挤、脏乱不堪。在过去的两年里，数以千万计的难民放弃了再度回到自己家园的希望，甚至不惜以生命为代价， 试图前往西方国家寻求庇护。

去年，二十二万难民跨过了地中海或爱琴海并到达了欧洲。今年至今为止，预估有三十五万人已经越过海峡，其中，至少有五千人死亡。

大多数难民前往意大利或匈牙利，因为这两个离他们最近的欧盟国家是申根地区的一部分。申根地区区包含了26个国家，这些国家不需要检查内部签证或护照。任何人一旦到达那些地方，就可以在欧洲畅行无阻。

不难相信ISIS 已经完成了它声称的在移民中潜入四千名特工的计划。就算只有一千或五百名特工都会对西方国家的安全造成极大的威胁。

加拿大已经同意接收11,300名叙利亚难民，其中2,200人已经抵达。

加拿大政府的计划和这些统计数字也许无法满足新民主党和自由党的难民政策。他们一心想利用Alan Kurdi的悲剧性死亡在大城市中吸引更多穆斯林民众的选票，进而对抗哈伯领导的保守党。

加拿大保守党目前执行的政策是——把潜在的恐怖分子从难民中筛查出来，让真正的难民进入加拿大。这无疑是正确的决定。

Whose heart did not ache when they saw the photo of Alan Kurdi’s body? Kurdi is the three-year-old Syrian refugee who drowned along with his mother Rehan and brother Ghalib while his parents were attempting to slip the family into Europe last week.

The photo of his lifeless body washed ashore on a Turkish beach, his angelic face in the sand, alerted the Western world to the refugee crisis unfolding in the Middle East as hundreds of thousands of displaced persons flee war in their homelands in search of asylum in Europe.

And what parent didn’t grieve with Alan’s father Abdullah who tried to rescue his wife and sons but watched them float away in especially rough seas that flipped the tiny, rickety fishing boat they were sailing in.

And who didn’t feel for Tima Kurdi, Abdullah’s sister and Alan’s aunt, a 20-year resident of Canada who now lives in the Vancouver suburb of Coquitlam, who learned her tiny, precious nephew was dead from seeing his photo online.

Their terrible losses made every Canadian rightly reconsider whether this country is doing enough to help the vulnerable innocents of the Middle East and North Africa.

But it is never a good idea to make policy with our hearts rather than our heads.

While Western nations, including Canada have a built-in moral urge to alleviate the suffering of Syrian and Libyan refugees (among others), we have to keep in mind that ISIS has threatened for a year to stir up a massive refugee migration to disguise an infiltration of its terrorists into the West.

It’s in the DNA of Western democracies and their citizens to want to open their doors, but to do so blindly is foolhardy.

The leaders of ISIS count on us to rush to the aid of hapless and hurting asylum seekers, to lower our guard (and the barriers at our borders) out of compassion.

Why wouldn’t they use the current crisis, whether or not they started it, to slip their operatives into the West? After all, even if we do not see ourselves at war with ISIS, these Muslim extremists see themselves at war with us.

The scope of the tragedy is staggering.

After four years of civil war in Syria and even more years of instability in Libya, millions have been forced from their homes into refugee camps in their own and neighbouring countries. The camps have become overcrowded and squalid, so in the past two years many hundreds of thousands have given up hope of ever returning home and sought to get to the West, even at the risk of their own lives.

Last year, 220,000 refugees crossed the Mediterranean or Aegean to Europe. So far this year, an estimated 350,000 have crossed. In the attempt, 5,000 have died.

Most head for Italy or Hungary because those are the closest EU countries that are part of the Schengen area – the zone that includes 26 countries where there are no internal visa or passport checks. Once there, they can move about Europe freely.

It is not hard at all to believe ISIS has fulfilled its claim to have snuck 4,000 agents in with the emigrants. Even 1,000 or just 500 would be an enormous threat to Western security.

Canada has agreed to take 11,300 Syrian refugees of whom 2,200 have already arrived.

This may not satisfy the NDP and Liberals who are so keen to attract Muslim voters in Canada’s largest cities that they have used little Alan Kurdi’s tragic death as a political club against the Harper Tories.

But the Tories are doing the right thing by letting refugees enter Canada only after screening out any potential terrorists in their midst.
